Description

  The present invention relates to a straddle type vehicle such as a motorcycle and the appearance parts thereof.

  In the two-wheeled motor vehicle, the appearance is enhanced by applying paint to external parts such as a fuel tank and a cowl (see, for example, Patent Document 1).

Unexamined-Japanese-Patent No. 5-76820

  By the way, in a straddle-type vehicle such as a motorcycle, there is a possibility that a driver may come in contact with external parts and cause scratching on a painted surface. Further, in the manufacturing process of the saddle-ride type vehicle, the appearance parts having a scratch on the coated surface are judged as rejection in the appearance inspection process, and are passed to the wound repair process. In particular, in the case where the color arrangement or the like of the appearance part makes the scratch on the coated surface more noticeable, there is a possibility that the appearance inspection step may be judged as rejection, and the manufacturing efficiency is lowered.

  An object of the present invention is to maintain the aesthetics of exterior parts of a straddle-type vehicle well and to improve the manufacturing efficiency of the straddle-type vehicle.

  A straddle-type vehicle according to an aspect of the present invention includes a first appearance component having an outer surface exposed to the outside of the vehicle, the first appearance component having a base and a coated portion coated on the base. The covering portion includes a colored layer and a light transmitting layer laminated on the colored layer to form the outer surface, and the light transmitting layer includes a self-repairing resin.

  According to the above configuration, when the outer surface of the first appearance part of the saddle-ride type vehicle is scratched, the elasticity of the self-healing resin causes the scratch to be self-repaired naturally. Therefore, even without special maintenance, it is possible to maintain good aesthetics in which external light is reflected by the colored layer through the light transmission layer to be visually recognized. Also, in the process of manufacturing a saddle-ride type vehicle, since the flaws (i.e., dents) attached to the outer surface of the appearance part are self-repaired, the rejection rate in the appearance inspection process is reduced. Therefore, the wound repair process for rejected products can be reduced, and the manufacturing efficiency of the straddle type vehicle can be improved.

  An appearance part of a saddle-ride type vehicle according to one aspect of the present invention is an appearance part having an outer surface exposed to the outside of a saddle-ride type vehicle, comprising: a base; and a coating portion coated on the base; The coating comprises a self-healing layer comprising a self-healing resin.

  According to the above configuration, as well as the above, the appearance of the appearance part of the straddle-type vehicle can be favorably maintained, and the manufacturing efficiency can be improved.

  According to the present invention, the aesthetics of the appearance part of the straddle type vehicle can be maintained well, and the manufacturing efficiency can be improved.

  Hereinafter, embodiments according to the present invention will be described with reference to the drawings. In addition, the concept of the direction used in the following description is based on the direction seen from the driver who got on the motorcycle.

  FIG. 1 is a side view of a motorcycle 1 according to an embodiment of the present invention. As shown in FIG. 1, the motorcycle 1 includes a front wheel 2 and a rear wheel 3. The front wheel 2 is connected to a front fork 4 and the front fork 4 is supported by a steering shaft (not shown) rotatably supported by the head pipe 5. A bar type handle 6 gripped by the driver R (passenger) is attached to the steering shaft so as to extend substantially in the lateral direction of the vehicle. The steering wheel 6 rotates to steer the front wheel 2 through the steering shaft by the operation of the driver R for steering the motorcycle 1. A pair of left and right main frames 7 extend rearward while tilting downward from the head pipe 5, and a pivot frame 8 is connected to the rear of the main frames 7. A front end portion of the swing arm 9 is pivotally supported by the pivot frame 8, and a rear wheel 3 is pivotally supported by a rear end portion of the swing arm 9. A fuel tank 10 is disposed behind the handle 6. Behind the fuel tank 10, a seat 11 on which the driver R sits is disposed.

  At least a part of the fuel tank 10 is located above the main frame 7, is adjacent to the seat 11 from the front side, and protrudes above the seat 11. The fuel tank 10 has a shape in which a central portion in the front-rear direction bulges left and right, and a lower rear portion of the fuel tank 10 is recessed inward in the vehicle width direction. That is, the left and right width of the lower rear portion of the fuel tank 10 is smaller than the left and right width of the central portion of the fuel tank 10 in the front-rear direction. The driver R holds a part of the fuel tank 10, in particular, the lower rear of the fuel tank 10 with the inner surface of the leg centered on the knee, and operates with the body of the driver R stabilized.

  A step 12 on which the driver R places a foot is disposed below the seat 11 and on both the left and right sides. The engine E supported by the main frame 7 and the pivot frame 8 is disposed between the front wheel 2 and the rear wheel 3. A transmission 13 is connected to the output shaft of the engine E, and the driving force output from the transmission 13 is transmitted to the rear wheel 3 via a chain or a belt. The front wheel 2 is covered by a fender 14 from above. The fender 14 is located in front of the handle 6.

  The motorcycle 1 includes a cowl which is an outer shell component disposed at the outermost position of the vehicle. The cowl is one of the appearance parts, for example, to guide the traveling wind to reduce air resistance, to suppress the flow of traveling wind to the driver, or to cover the internal parts to improve the design. Used. For example, the cowl is often colored, and letters and patterns are often visually represented. In the present embodiment, the cowl is one of resin parts made of a resin material. The cowl may include a front cowl, a side cowl, a seat cowl, a rear cowl, and the like.

  A pair of side cowls 15 is provided from the front of the head pipe 5 to the left and right outside of the engine E. The fuel tank 10, the fender 14 and the side cowl 15 are exterior parts having an outer surface exposed to the outside of the motorcycle 1. The appearance part is a part having an exposed surface that is exposed as the outer surface of the vehicle when attached to the vehicle. In the present embodiment, the vehicle forms an appearance shape of the entire vehicle by combining a plurality of appearance parts. The outer surface of the fuel tank 10 and the side cowl 15 has an area disposed on the rear side of the handle 6 and on the front side of the seat 11.

  FIG. 2 is an enlarged cross-sectional view of the main part of the fuel tank 10 of the motorcycle 1 shown in FIG. As shown in FIG. 2, the fuel tank 10 has a base 16 which is a container in which a fuel storage space is formed, and a covering portion 17 painted on the outer surface of the base 16. In the present embodiment, the base portion 16 is formed of a metal material, specifically, an aluminum alloy. However, the base 16 of the fuel tank 10 may be formed of resin (for example, polypropylene resin, polyethylene resin, fiber reinforced resin, etc.). The covering portion 17 is formed by laminating the primer layer 21, the colored layer 22, the metal coating layer 23, and the light transmitting layer 24 in this order. The primer layer 21 is an undercoat for preventing rusting of the metal base 16. The colored layer 22 is a layer provided to provide a visible color tone as the outer surface of the appearance part. The colored layer 22 is set to a predetermined color tone by containing a pigment in the layer. In the present embodiment, a pigment having a color tone different from that of the base 15 is included in the layer. The colored layer 22 expresses the color tone of the fuel tank 10 and secures the adhesion between the primer layer 21 and the metal coating layer 23. In the present embodiment, the colored layer 22 contains a dark (for example, black, amber, blue, etc.) pigment having a lightness of 0% or more and less than 50%.

  The metal coating layer 23 is formed by depositing a metal on the surface of the colored layer 22. In the present embodiment, the metal coating layer 23 is silver mirror coating. The metal coating layer 23 may be a plating using a metal such as aluminum, in addition to the silver mirror coating. The metal coating layer 23 is thinner than any of the colored layer 22 and the light transmitting layer 24. For example, the metal coating layer 23 has a film thickness of 0.02 μm or more and 0.1 μm or less. In the present embodiment, the metal coating layer 23 has light transparency. That is, the metal coating layer 23 functions as a so-called half mirror by adjusting the thickness appropriately. Therefore, when the metal coating layer 23 is viewed from the outside, depending on the angle at which the appearance component is seen with respect to the light source, it may be visible as a mirror surface appearance by light reflection, or the color of the colored layer 22 may be visible as an appearance through the metal coating layer 23 To The metal coating layer 23 may be a layer that produces a color tone having high light reflectance such as metallic gloss.

  The light transmitting layer 24 formed on the outer surface side of the appearance part than the colored layer 22 has a light transmitting property because the light transmitting material is contained in the layer. With respect to the light transmission, the light transmission has at least a degree of transmission capable of entering and reflecting light to the colored layer 22. As a result, even if the light transmission layer 24 is formed outside the colored layer 22, the color tone colored by the colored layer 22 can be made visible. The light transmission layer 22 may function as a protective layer.

  The light transmission layer 24 is formed by laminating the first light transmission layer 31 and the second light transmission layer 32. The first light transmission layer 31 is formed of a transparent coating agent made of a non-self-healing resin. This non-self-repairing resin (non-self-repairing layer) causes a scratch with a pencil of F or more in the scratch hardness test (pencil method) defined in JIS K5600-5-4 (1999), and the scratch is time It becomes a permanent depression which does not recover even if it passes. In the present embodiment, the first light transmitting layer 31 is composed of a main agent (trade name: FG clear, product number: 4207-06578, Saito Paint Co., Ltd.) and a curing agent (trade name: FG clear curing agent, product number: 6508- 0005784, Saito Paint Co., Ltd.). The first light transmission layer 31 is thicker than the colored layer 22. A silanol group is provided between the first light transmission layer 31 and the metal coating layer 23 to ensure the adhesion between the first light transmission layer 31 and the metal coating layer 23.

  The second light transmission layer 32 is formed of a transparent coating agent made of or containing a self-healing resin. The second light transmission layer 32 is thicker than the colored layer 22. The second light transmitting layer 32 has a light transmitting property, and functions as a self-repairing layer having a self-repairing function by containing a self-repairing resin. The self-healing resin is a resin that, when formed as a coating layer, gives the coating layer flexibility, in other words, elastic recovery. The self-repairing layer formed of the self-repairing resin dents and receives an external force or an impact that may cause a scratch to elastically recover. Specifically, the self-repairing layer has a resin skeleton structure composed of a combination of a part having a hard property (hard segment) and a part having a deformable property (soft segment). Thus, the self-repairing layer has an elastic recovery function as if it were a trampoline. For example, a self-healing resin is realized by an acrylic urethane resin. A resin for forming a coating film layer having such a self-repairing function (elastic recovery function) is a self-repairing resin. An appearance part having a self-repairing layer and having a self-repairing function is referred to as a first appearance part. Also, an appearance part that does not have a self-repairing layer and does not have a self-repairing function is referred to as a second appearance part.

  The outer surface 32 a of the second light transmission layer 32 (self-repairing layer) is an outer surface exposed to the outside of the fuel tank 10. This self-repairing layer recovers the flaw by the elastic restoring force of the self-repairing resin itself when it is deformed by external force and a flaw is generated. In the present embodiment, “scratch” means a recess which is deformed inward from the surface by an external force, and includes a recess before a restoring force is generated by the self-repairing resin. In the self-repairing resin, a recess deformed by an external force less than the recovery limit is elastically recovered by the recovery force over time, and the recess is repaired. This prevents them from remaining as scratches after restoration.

  For example, the self-repairing resin (self-repairing layer) used in the present embodiment recovers the flaw by 10 to 20 minutes after the occurrence of the flaw under the environment of the ambient temperature (for example, 26 ° C. or 30 ° C.) It is a thing. The self-repairing resin preferably recovers within 30 minutes, preferably 15 minutes, at ambient temperature (for example, 26 ° C. or 30 ° C.) when a restoringly acceptable external force is applied.

  The self-repairing resin (self-repairing layer) preferably has a pencil hardness of 2 B or more in the scratch hardness test (pencil method) defined in JIS standard (JIS K 5600-5-4 (1999)), and has B or more It is further preferable that it is pencil hardness. That is, it is preferable that the self-repairing resin (self-repairing layer) has a hardness that does not generate a scratch with a 3B pencil and that a scratch occurs immediately after the test with a 2B or more pencil or a B or more pencil. Even if the self-repairing layer is scratched with a pencil of a predetermined hardness immediately after the scratch test, the self-repairing function can restore the scratch over time by the self-repairing function. In the present embodiment, the hardest pencil hardness which is not scarred immediately after the scratch test is defined as the pencil hardness of the self-repairing paint. In addition, as a result immediately after the test, the time required for the self-repairing of the flaw attached to the self-healing resin (self-repairing layer) is shorter in the case of 2B than in the case of the pencil hardness of B, but the pencil hardness is 2B In the case of B, the uniformity of polishing in the polishing process of the outer surface (self-healing resin) before shipping of the motorcycle 1 is higher than in the case of B.

  If the self-healing resin has a hardness of less than B, the swelling phenomenon is not eliminated when the state of the self-healing resin adhering to gasoline continues, and the appearance decreases. When the hardness is B or more, the swelling phenomenon does not occur, or even if it occurs, it can be resolved by time lapse. Thus, in order to improve the gasoline resistance, it is preferable that the pencil hardness is B or more. In other words, it is preferable that setting is performed so that even if the temperature exceeds 23 minutes, restoration is not sufficient and scratches remain, and after 10 minutes, the scratches are sufficiently restored. Alternatively, it is preferable that the wound remains even after 1 minute at 30 ° C., and the wound is sufficiently restored after 5 minutes. As another example, the wound may remain even after 5 minutes under the condition of 30 ° C., and the wound may be set to sufficiently recover after 10 minutes. By setting the hardness, in other words, the hardener density and the crosslink density, to such an extent that they do not sufficiently recover until exceeding a predetermined time (for example, one minute), self-repairing performance is maintained while satisfying gasoline resistance. A self-repairing layer can be suitably used as an exterior part for a vehicle.

  The self-repairing resin (self-repairing layer) preferably has a pencil hardness of F or less in the scratch hardness test (pencil method) defined in JIS standard (JIS K5600-5-4 (1999)), and HB It is further preferable that it is the following pencil hardness. In the present embodiment, the second light transmission layer 32 is formed by mixing the main agent (trade name: KJY31, Natco Co., Ltd.) and the curing agent (trade name: KJY31 curing agent, Natco Co., Ltd.).

  Further, in the present embodiment, as hardness to maintain the restorability, HB or less is preferable when the base 16 is a resin, and H or less is preferable when the base 16 is a metal. From this, by setting the hardness to HB or less, the self-repairing layer can be made common regardless of the material of the base. Further, according to the scratch test, the self-repairing layer 32 of the present embodiment showed a scratch recovery effect after the lapse of the recovery time even if the pencil hardness is 4H. On the other hand, in the case of the non-self-repairing layer, the occurrence of a scratch with a pencil having a hardness of F was observed.

  In the present embodiment, it is easy to determine the presence or absence of the flaw repair work generated in the manufacturing process by quickly recovering the flaw in the self-healing resin. However, it is preferable that the self-repairing layer be set hard enough not to restore sufficiently within a predetermined time, for example, within one minute, preferably within three minutes after the occurrence of a flaw. As a result, while maintaining the condition required as the appearance part of the vehicle, for example, the hardness for easy repair work and the gasoline resistance, the restoration effect is easily exhibited.

  In this embodiment, a friction member having a rectangular shape of 20 mm is used to apply a force of 5 N (500 gf) to the friction member with the cotton cloth sandwiched between the friction member and the outer surface of the self-repairing layer. Slide it. Further, using a similar friction element, a force of 10 N (1000 gf) was applied to the friction element to slide the skin in a state in which the skin was sandwiched between the friction element and the outer surface of the self-repairing layer. In such a test, in the case of a non-self-repairing layer having a pencil hardness of F without a self-repairing layer, visual flaws were observed. On the other hand, in the case of the self-repairing layer of the present embodiment, no scratch was visually observed at least after 10 minutes, and it was found that the self-repairing layer had sufficient recovery.

  FIG. 3 is an enlarged sectional view of an essential part of the side cowl 15 of the motorcycle 1 shown in FIG. In the present embodiment, the side cowl 15 is one of resin parts made of a resin material. As shown in FIG. 3, the side cowl 15 has a base 18 made of a synthetic resin and a coating 19 coated on the outer surface of the base 18. The covering portion 19 is formed by laminating the conductive primer layer 41, the colored layer 42, the metal coating layer 43, and the light transmitting layer 44 in this order, and the light transmitting layer 44 includes the first light transmitting layer 51 and the first light transmitting layer 51. The second light transmission layer 52 is laminated. The second light transmitting layer 52 has a light transmitting property and also contains a self-repairing resin, thereby functioning as a self-repairing layer having a self-repairing function. The outer surface 52 a of the second light transmitting layer 52 is an outer surface exposed to the outside of the side cowl 15. The conductive primer layer 41 is an undercoat for providing adhesion between the base 18 made of resin and the colored layer 42 and for electrostatically coating the colored layer 42. The colored layer 42, the metal coating layer 43, and the light transmitting layer 44 of the side cowl 15 are the same as the colored layer 22, the metal coating layer 23, and the light transmitting layer 24 of the fuel tank 10, respectively. The layer 51 and the second light transmission layer 52 are the same as the first light transmission layer 31 and the second light transmission layer 32 of the fuel tank 10, respectively.

  The outer surface of the appearance component disposed on the front side of the handle 6 or the rear side of the sheet 10 may be formed of a transparent coating agent made of a non-self-healing resin. In addition, the outer surface of the appearance component having a bright color of 50% to 100% of the lightness of the colored layer of the covering portion may be formed of a transparent coating agent made of a non-self-healing resin. As an example, the outer surface of the fender 14 (see FIG. 1) may be formed of a transparent coating agent made of a non-self-healing resin. That is, the fender 14 has a base made of a synthetic resin and a covering portion laminated on the base, and the covering portion has a colored layer and a metal coating layer, but the light transmission to be laminated on the metal coating layer The layer may be made of a non-self-healing resin without having a self-healing resin.

  According to the configuration described above, when the fuel tank 10 of the motorcycle 1 and the outer surfaces 32a and 52a of the side cowl 15 are scratched, the elasticity of the self-repairing resin which is the second light transmitting layer 32 or 52 is used. Wounds (ie, dents) are self-healing naturally. Therefore, even without special maintenance, the external light can be well reflected by the colored layers 22 and 42 through the light transmitting layers 24 and 44, and the aesthetic appearance can be well maintained. And since a saddle-ride type vehicle is relatively small compared to a four-wheeled vehicle because it is driven across, it is easy to look over the entire vehicle body and it is easy to be noticeable when a scratch occurs, but according to this configuration, the scratch is Since sticking can be prevented, the aesthetic appearance as the motorcycle 1 can be easily maintained.

  Further, also in the manufacturing process of the motorcycle 1, since the flaw attached to the outer surfaces 32a and 52a of the fuel tank 10 and the side cowl 15 is self-repaired, the rejection rate in the appearance inspection process is reduced. Therefore, the work for preventing the damage can be reduced or omitted, and the process of repairing the rejected product can be reduced, and the manufacturing efficiency of the motorcycle 1 can be improved. Also, for example, it may be possible to eliminate a protective sheet that protects the appearance parts from being scratched. By eliminating the process of attaching and detaching the protective sheet as described above, the manufacturing efficiency can be further improved. The effect of the present invention is high in the case of a motorcycle 1 assembled by a worker by hand.

  In particular, when a scratch occurs when the metal coating layers 23 and 43 are formed, the reflected light from the metal coating layers 23 and 43 may scatter at the scratched portions, causing the scratched portions to be white and noticeable. In the present embodiment, the appearance component provided with such metal coating layers 23 and 43 can be prevented from being easily scratched, so the appearance improvement effect can be increased.

  Further, since the pencil hardness of the self-repairing resin (self-repairing layer) is 2 B or more, more preferably B or more, when a flaw is found before shipping the motorcycle 1, the fuel tank 10 and / or the side cowl 15 In the step of repairing and polishing the outer surfaces 32a and 52a, it is possible to prevent the outer surfaces 32a and 52a from being too soft and polishing being uneven. In addition, if the pencil hardness is 2 B or more, it is possible to prevent the possibility of being easily scratched excessively in the manufacturing process and to prevent the generation of useless work. Therefore, the self-repairing performance, the polishing performance and the workability can be compatible. In addition, when the pencil hardness of the self-healing resin is 2 B or more, preferably B or more, gasoline resistance can be enhanced. Specifically, when the self-healing resin is too soft, it swells and the coating film is softened. In the present embodiment, by setting the pencil hardness of the self-healing resin to 2 B or more, particularly B or more, preferable durability can be obtained as an appearance part of a saddle-ride type vehicle traveling with gasoline as fuel.

  In addition, since the pencil hardness of the self-healing resin is F or less, and more preferably HB or less, it is prevented that the time from self-healing to a long time from the occurrence of a scratch is generated in the manufacturing process of the motorcycle 1 It is possible to increase the probability that the scratch has been self-repaired by the appearance inspection process. Therefore, the rejection rate in the appearance inspection step is further reduced, and the manufacturing efficiency of the motorcycle 1 is further improved.

  The straddle-type vehicle is operated by the driver straddling the appearance component that constitutes the outer surface of the vehicle, so that the driver has more contact with the surface of the appearance component than the four-wheel vehicle during driving. Specifically, the driver's driving with both legs holding the vehicle body makes contact between the clothes of the legs and the side surface of the vehicle body. In addition, when moving the posture in order to incline the vehicle body at the time of turning, there is a case where the user wears between the clothes and the side surface of the vehicle body. Similarly, when the driver's center of gravity is moved in the vertical direction, or when getting on and off, rubbing may occur between the clothes and the side of the vehicle body. When the driver leans forward to reduce air resistance during traveling, the chest clothing and the surface of the fuel tank may contact or rub against each other. For example, the portion of the leg in contact with the clothes is a side portion of the vehicle body located forward of the seat and lower than the upper surface of the seat. Specifically, the portion that rubs with the clothes is a side cowl corresponding to the side surface of the vehicle below the fuel tank, a side portion of the fuel tank that is the front portion from the seat, or a tank cover that covers the side surface of the fuel tank. May be In the above-described configuration, the fuel tank 10 and the outer surfaces 32a and 52a of the side cowl 15 disposed on the front side of the seat 10 seated by the driver R straddling and behind the handle 6 gripped by the driver R are self-repairing Since it has, the appearance of the part which a driver | operator's R clothes etc. contact and a scratch may generate | occur | produce can be favorably maintained while boarding. In addition, by providing a self-healing resin layer also on the side cowl behind the driver's seat, it is possible to suppress damage caused by the contact between the driver of the passenger (occupant) and the surface of the appearance parts, as well as the driver. It is possible to suppress the damage caused by attaching and removing the In this way, the part that wears with the clothes may be a cowl portion below the passenger seat.

  Moreover, when the colored layers 22 and 42 are visually recognized as an appearance, a damaged part may be noticeable in comparison with the colored layers 22 and 42. The colored layers 22 and 42 of the fuel tank 10 and the side cowl 15 have a dark color with a brightness of 0% or more and less than 50%. Therefore, when the outer surfaces 32a and 52a are scratched, the area appears dark by the colored layers 22 and 42. On the other hand, although the blemish looks whitish and becomes noticeable, since the blemish is self-repaired by the elasticity of the self-healing resin, it is possible to exert an excellent effect in terms of maintaining aesthetic appearance and manufacturing efficiency.

  Further, by providing a self-healing resin on the appearance parts covering the upper side and the side of the engine E which is the heat source, for example, the fuel tank 10 and the side cowl 15, the appearance parts are warmed by the heat of the engine E It is possible to enhance the resin recovery function.

  In addition, since the first light transmission layers 31 and 51 are non-self-healing resin and the second light transmission layers 32 and 52 are self-healing resin, the first light transmission layers 31 and 51 and the second light transmission layer 32 are The self-repairing resin can be used only for the second light transmitting layers 32 and 52 while sufficiently absorbing the ultraviolet rays of the incident light and the reflected light using both of them. Therefore, the ultraviolet ray absorbing performance can be enhanced and the amount of the self-healing resin used can be suppressed.

  Further, as described above, the appearance parts which the clothes contact during operation are the first appearance parts provided with the self-healing resin, and the appearance parts such as the fender and the front cowl which are less likely to come in contact with the clothes The self-healing coating was applied to the second appearance component provided with the non-self-healing resin without providing the self-healing resin, as compared with the case where the self-healing resin is provided for the appearance components of the entire vehicle body. By reducing special parts and reducing costs, it is possible to prevent damage caused by clothing. Wounding can be effectively prevented by using the self-healing resin only for the part that is easily damaged, not limited to the part that contacts clothing during operation.

  A self-healing resin may be used as an appearance part including the periphery of a part where a key is inserted as an appearance part which is easily damaged other than the part in contact with clothing. By this, even if the key accidentally touches the periphery of the insertion opening during the insertion operation of the key, it is possible to prevent the damage at the contact site and to make it easy to maintain the aesthetic appearance. In addition, self-healing is also possible for external parts including the area where a fastening member such as a bolt is inserted for attaching external parts and attaching / detaching internal parts, and around the area where tools are inserted for adjusting internal parts. Resin may be used.

  As a modification, a particulate bright material may be dispersed between the metal coating layer of the fuel tank 10 or the side cowl 15 described above and the light transmitting layer. As the glitter material, for example, aluminum flakes (pieces obtained by finely cutting aluminum foil), glass flakes, pearl pieces (mica pieces), or a combination thereof can be used. In this case, when the outer surface of the fuel tank 10 and the side cowl 15 is scratched, the reflected light from the glittering material makes the scratches more noticeable, but the elasticity of the self-healing resin of the second light transmitting layers 32 and 52 causes the scratches. Is naturally self-repairing and effective in terms of aesthetic maintenance and manufacturing efficiency.

  FIG. 4 is an enlarged cross-sectional view of the main part of the fuel tank 110 of the modification. As shown in FIG. 4, in the fuel tank 110, the light transmission layer 32 is stacked directly on the colored layer 22. That is, the metal coating layer 23 and the first light transmitting layer 31 of the non-self-healing resin are omitted. With such a configuration as well, the aesthetics of the appearance part (fuel tank 110) can be favorably maintained, and the manufacturing efficiency can be improved. That is, even when the metal coating layer is not formed, the self-healing resin can self-heal a scratch, thereby making it possible to prevent the marked portion from being marked with respect to the colored layer. The effect is particularly large when the colored layer is black or a color close to black. Even when the colored layer is white or a color close to white, the effect of being able to prevent the appearance of scratches can be achieved.

  FIG. 5 is a cross-sectional view of the main part of the side cowl 15 of the modification. As shown in FIG. 5, mounted components 60 and 62 (for example, a support member, a coolant tank, etc.) attached to the side cowl 15 are disposed on the inner surface side of the side cowl 15 in a state attached to the vehicle body. There is. The mounted members 60 and 62 are components supported by the cowl in a state where the cowl is mounted to the vehicle body. In other words, at least a part of the mounted members 60 and 62 is covered by the cowl, whereby the portion exposed to the outside of the vehicle body is suppressed. The mounted member may include a support component for causing the cowl to support another mounted component such as a support member (bracket). In particular, the sub-unit in which the mounting member is attached to the cowl is fixed to the vehicle body frame or a stay supported by the vehicle body frame.

  A mounting hole 15a and a mounting seat 15b are formed in the side cowl 15 as a mounting portion, and the mounting part 60 is mounted to the side cowl 15 by a fixture 61 (for example, a rivet) inserted into the mounting hole 15a. The attachment part 62 is attached to the side cowl 15 by a fixing member (for example, a bolt or a screw) on the attachment seat 15 b. In such a configuration, in the sub-unit formation process of the cowl, the mounted component is attached to the cowl while holding the outer surface of the cowl, and the tool, parts, etc. contact the outer surface of the side cowl 15 and scratch is generated. Because it is easy to stick, the self-healing resin increases the self-healing effect of the wound.

  FIG. 6 is an enlarged cross-sectional view of the light transmission layer 32 of another modification. As shown in FIG. 6, an uneven shape may be formed on the outer surface 32 a of the light transmission layer 32 formed of the self-repairing resin. For example, the light transmitting layer 32 may be provided with a concavo-convex shape on the outer surface 32 a by including at least the outer surface 32 a of matting particles 70 as a matting agent. The matting particles 70 are particles for forming asperities on the outer surface of the appearance part, and are contained in a paint for forming the outermost layer of the appearance part. The matting particle 70 partially protrudes from the outer surface of the appearance component to form asperities on the surface of the appearance, thereby exerting the function of suppressing the gloss of the outer surface 32a by utilizing irregular reflection of light, for example, gloss As the erasing particles 70, particles such as silica may be used. Under the light transmission layer 32, a metal coating layer may or may not be present.

  Thus, by providing the convex portion (particle 70) for matting on the self-healing resin, the clothes of the driver R and the like are rubbed against the outer surface 32a of the light transmission layer 32, and the convex portion (particle 70) is formed. Even when an external force is applied, the external force is absorbed by the elasticity of the light transmission layer 32 which is a self-healing resin, and the convex portion (particle 70) drops out of the light transmission layer 32 or is buried in the light transmission layer 32. Is suppressed. Therefore, by using the self-healing resin on the outermost surface of the appearance part to which the matting agent is applied, the matting effect can be maintained for a long time, and the appearance can be kept good.

  From the above description, many modifications and other embodiments of the present invention will be apparent to those skilled in the art. Accordingly, the above description should be taken as exemplary only, and is provided for the purpose of teaching those skilled in the art the preferred modes of carrying out the present invention. The structural and / or functional details may be substantially altered without departing from the spirit of the present invention. For example, the outer surface of the light transmission layer may be further provided with another functional surface layer, specifically, a water repellent cured layer (eg, glass coating). When the sticker is attached to the portion of the appearance part to be coated with the self-healing resin, the outer surface of both the sticker and the appearance part may be collectively coated with the self-healing resin. Alternatively, the outer surface of the sticker itself may be coated with a self-healing resin. The self-repairing resin forming the light transmission layer is preferable because it can be overcoated with the self-repairing resin if it does not contain a water repellent group.

  The metal coating layer may not have light transparency. That is, a metal coating layer having a thickness to be a full mirror may be formed. Even in this case, by preventing the damaged portion, it is possible to prevent the appearance of the damaged portion due to the reflected light from the metal coating layer being scattered at the damaged portion.

  It is preferable that a self-repairing resin be used at a portion where the driver or a passenger's clothes come in contact, but a self-repairing paint may be used at other portions. For example, the self-repairing paint may be applied to the entire portion to be the appearance. That is, self-repairing resin may be provided for other cowls such as the front cowl other than the side cowl.

  As described above, the present invention is the case in which glitter particles are mixed as a metal coating layer to make the appearance metallic, or in the case where a matting agent is mixed so as to make the appearance matte. Can be applied. In the present embodiment, a matte shape is formed on the surface to form a textured shape using a matting agent, and a matte texture is obtained. However, even when a textured shape is formed by devising a coating method, the present invention is similarly applied. The invention can be applied. In addition, even when the unevenness is formed for the purpose other than the matting, it is possible to prevent the disappearance of the unevenness, and it is easy to maintain the function of the unevenness.

  As another example, a colored layer may not be provided when the base itself is colored, as in a pigmented resin material. The colored layer may also contain a self-healing paint. That is, if the colored layer doubles as a self-repairing layer, the light transmitting layer may not be necessary. A light transmission layer made of a self-healing resin may be provided on the outer surface of the frame which is to be an appearance part. For example, when there is a frame member in the knee grip portion which is under the fuel tank and in front of the driver's seat and the vehicle width dimension is narrower than the remaining portions on both sides in the front and rear direction. The knee grip portion of the frame member may be provided with a colored layer and a light transmission layer of a self-healing resin laminated thereon.

  The exterior part disposed on the front side of the seat and on the rear side of the handle and projecting upward from the seat may be a fuel tank cover. When the two-wheeled motor vehicle is an electric vehicle without an internal combustion engine, a dummy tank or a tank is disposed instead of the fuel tank as an external component disposed on the front side of the seat and the rear side of the steering wheel and projecting above the driver's seat. It may be a cover. In addition, although a motorcycle has been illustrated as a saddle-ride type vehicle, any vehicle may be used as long as the driver sits on a seat, for example, an ATV (All Terrain Vehicle) or a small watercraft.

FIG. 2 is an enlarged cross-sectional view of the main part of the fuel tank 10 of the motorcycle 1 shown in FIG. As shown in FIG. 2, the fuel tank 10 has a base 16 which is a container in which a fuel storage space is formed, and a covering portion 17 painted on the outer surface of the base 16. In this embodiment, the base 16 is formed of metal materials. However, the base 16 of the fuel tank 10 may be formed of resin (for example, polypropylene resin, polyethylene resin, fiber reinforced resin, etc.). The covering portion 17 is formed by laminating the primer layer 21, the colored layer 22, the metal coating layer 23, and the light transmitting layer 24 in this order. The primer layer 21 is an undercoat for preventing rusting of the metal base 16. The colored layer 22 is a layer provided to provide a visible color tone as the outer surface of the appearance part. The colored layer 22 is set to a predetermined color tone by containing a pigment in the layer. In the present embodiment, a pigment having a color tone different from that of the base 15 is included in the layer. The colored layer 22 expresses the color tone of the fuel tank 10 and secures the adhesion between the primer layer 21 and the metal coating layer 23. In the present embodiment, the colored layer 22 contains a dark (for example, black, amber, blue, etc.) pigment having a lightness of 0% or more and less than 50%.

If the self-healing resin has a hardness of less than B, the swelling phenomenon is not eliminated when the state of the self-healing resin adhering to gasoline continues, and the appearance decreases. When the hardness is B or more, the swelling phenomenon does not occur, or even if it occurs, it can be resolved by time lapse. Thus, in order to improve the gasoline resistance, it is preferable that the pencil hardness is B or more. In other words, it is preferable that setting is performed so that even if the temperature exceeds 23 minutes, restoration is not sufficient and scratches remain, and after 10 minutes, the scratches are sufficiently restored. Alternatively, it is preferable that the wound remains even after 1 minute at 30 ° C., and the wound is sufficiently restored after 5 minutes. As another example, the wound may remain even after 5 minutes under the condition of 30 ° C., and the wound may be set to sufficiently recover after 10 minutes. Thus to an extent not sufficiently restored to exceed a predetermined time (e.g., 1 minute), hardness, by cross-linking density is set in other words, to maintain the self-repairing performance while satisfying the gasoline resistance, for a vehicle Preferably, a self-repairing layer can be used as an appearance component of
