Description

The present invention relates to body covers.

In general, a straddle-type vehicle is provided with various cover members as a vehicle exterior on a vehicle body frame. BACKGROUND ART As a straddle-type vehicle, one having a body cover that forms the side surface of the front portion of the vehicle is known (see, for example, Patent Document 1). The body cover described in Patent Document 1 is arranged behind the front cowl so as to cover the head pipe, the radiator, and the like from the sides. The lower part of the front fork protrudes forward from the body cover, exposing the front wheel supported by the lower part of the front fork. When the straddle-type vehicle is running, running wind enters the inside of the body cover in the left-right direction to cool the radiator and the like.

By the way, if the lateral width of the body cover is reduced in order to reduce running resistance, muddy water splashed up by the front wheels may pass through the sides of the body cover and hit the occupant. On the other hand, increasing the lateral width of the body cover suppresses the adhesion of muddy water to the occupants, but increases running resistance. In this way, there was a trade-off relationship between the difficulty of muddy water adhesion and the reduction in running resistance.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a body cover capable of reducing running resistance due to running wind while suppressing muddy water from adhering to a passenger.

A body cover according to one aspect of the present invention is a body cover for a straddle-type vehicle in which a front wheel is supported by a front portion of a vehicle body frame, comprising: a base body cover covering the vehicle body frame from the sides above the front wheel; and the base body cover. an outer body cover attached to the outside of the base body cover, the base body cover has a stepped surface formed by protruding laterally outward at the lower side than the upper side of the outer side surface of the base body cover, and the outer body cover includes the The above problem is solved by forming the eaves-like plate-like portion so as to cover the step surface from above.

According to the body cover of one aspect of the present invention, even if muddy water is splashed up by the front wheel and splashed above the stepped surface, the muddy water is received by the eaves-like plate-like portion of the outer body cover. Therefore, muddy water is prevented from adhering to the occupant of the straddle-type vehicle. In addition, the stepped surface and the eave-shaped plate-like portion form a path for running wind, and the running wind entering between the stepped surface and the plate-like portion is straightened rearward. Therefore, the running resistance of the straddle-type vehicle due to running wind is reduced. Therefore, it is possible to reduce running resistance while suppressing adhesion of muddy water to the occupant.

A body cover according to one aspect of the present invention is attached to a straddle-type vehicle in which a front wheel is supported by a front portion of a vehicle body frame. The body cover covers the body frame from the sides above the front wheels with the base body cover, and the outer body cover is attached to the outside of the base body cover. The base body cover is formed with a stepped surface in which the lower side of the outer surface of the base body cover protrudes laterally outward from the upper side, and the outer body cover is formed with an eave-shaped plate-like portion that covers the stepped surface from above. It is Even if muddy water is splashed up by the front wheels and splashed above the step surface, the muddy water is received by the eaves-like plate-like portion of the outer body cover. Therefore, muddy water is prevented from adhering to the occupant of the straddle-type vehicle. Further, the stepped surface and the eaves-like plate-like portion form a path for running wind, and the running wind entering between the stepped surface and the plate-like portion is straightened rearward. Therefore, the running resistance of the straddle-type vehicle due to running wind is reduced. Therefore, it is possible to reduce running resistance while suppressing adhesion of muddy water to the occupant.

A straddle-type vehicle to which the body cover of this embodiment is applied will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of a vehicle front portion of a straddle-type vehicle of this embodiment. In the following figures, an arrow FR indicates the front of the vehicle, an arrow RE indicates the rear of the vehicle, an arrow L indicates the left of the vehicle, and an arrow R indicates the right of the vehicle.

As shown in FIG. 1, the straddle-type vehicle 1 is configured by mounting various parts such as an engine 16 and an electrical system on a twin-spar vehicle body frame 10 formed by aluminum casting. The vehicle body frame 10 has a pair of main frames 12 that branch left and right from the head pipe 11 and extend rearward, and a pair of down frames 13 that branch left and right from the head pipe 11 and extend downward. A pair of main frames 12 support the rear portion of the engine 16 , and a pair of down frames 13 support the front portion of the engine 16 . By supporting the engine 16 on the body frame 10, the rigidity of the entire vehicle is ensured.

A front portion of the main frame 12 serves as a tank rail, and a fuel tank 17 is arranged on the tank rail. A rear portion of the main frame 12 is a body frame, and a seat rail 14 and a backstay 15 extend rearward from the upper portion of the body frame. A rider seat 18 is arranged on the seat rails 14 . A pair of front forks 21 are steerably supported by the head pipe 11 via a steering shaft (not shown). A front wheel 22 is rotatably supported by the lower portion of the front fork 21 , and the upper portion of the front wheel 22 is covered by a front fender 23 .

A radiator 24 is arranged below the head pipe 11 and in front of the cylinder head of the engine 16 . The radiator 24 is provided with a radiator core having a large number of thin tubes or radiating fins. Heat exchange is performed between the coolant flowing through the radiator core and the running wind blown against the radiator core. A headlamp unit 25 is provided in front of the head pipe 11 . The headlamp unit 25 is formed vertically, and two light emitting portions are arranged vertically. A headlamp cover 26 is attached around the headlamp unit 25 .

A pair of body covers 30 are attached to the straddle-type vehicle 1 to cover the front portion of the vehicle body frame 10 from the left and right sides. As described above, the front wheels 22 are supported by the front portion of the vehicle body frame 10 , and each body cover 30 is positioned above the front wheels 22 . At this time, it is preferable to increase the lateral width of each body cover 30 in order to prevent muddy water splashed up by the front wheels 22 from adhering to the occupant. Therefore, the body cover 30 of this embodiment is formed in a cover shape that functions as a mudguard against muddy water splashed up on the front wheels 22 and as a passage for the running wind.

The detailed configuration of the body cover will be described below with reference to FIGS. 2 to 4. FIG. FIG. 2 is a left side view of the vehicle front portion of this embodiment. FIG. 3 is a left side view of the vehicle front portion of the present embodiment with a part of the body cover removed. FIG. 4 is a front view of the vehicle front portion of this embodiment.

As shown in FIGS. 2 to 4 , the body cover 30 is arranged behind the headlamp cover 26 and together with the headlamp cover 26 forms the vehicle front exterior of the straddle-type vehicle 1 . The body cover 30 has a base body cover 31 fixed to the front portion of the vehicle body frame 10, an upper body cover 61 and an outer body cover 51 outside the base body cover 31, and an inner body cover 65 inside the base body cover 31. . An outer body cover 51 is arranged from an intermediate portion to a lower portion of the outer surface of the base body cover 31 , and an upper body cover 61 is arranged above the outer surface of the base body cover 31 .

The base body cover 31 laterally covers the body frame 10 (main frame 12 ) above the front wheels 22 and laterally covers the radiator 24 behind the front wheels 22 . The base body cover 31 has an upper half portion 32 with a small lateral width and a lower half portion 33 with a large lateral width. The outer surface of the lower half portion 33 protrudes laterally outward from the outer surface of the base body cover 31, that is, the outer surface of the upper half portion 32, to form a stepped surface 34 (see FIG. 4 in particular). there is The stepped surface 34 extends obliquely upward rearward from the front edge of the base body cover 31, and the base body cover 31 is divided into an upper half portion 32 and a lower half portion 33 with the stepped surface 34 as a boundary.

The front edge of the stepped surface 34 is positioned above the upper end of the front wheel 22 . A longitudinal groove 35 is formed by partially notching an intermediate position in the extending direction of the step surface 34 . The longitudinal groove 35 extends toward an opening 36 of the lower half 33, which will be described later. A stepped surface 34 is divided into a front half portion and a rear half portion with a longitudinal groove 35 interposed therebetween, and an elongated hole 37 is formed along the stepped surface 34 above the front half portion of the stepped surface 34 so that the rear half portion of the stepped surface 34 is formed. A projecting portion 38 is formed along the step surface 34 on the upper side. A plate-like portion 52 of an outer body cover 51 , which will be described later, is attached to the elongated hole 37 , and the upper surface of the projecting portion 38 is formed so as to be continuous with the upper surface of the plate-like portion 52 .

A lower half portion 33 of the base body cover 31 is formed with an opening 36 having a triangular shape in a side view below the step surface 34 . The opening 36 connects the inner side and the outer side of the base body cover 31 on the side of the radiator 24 and in front of the main frame 12 . Although the details will be described later, running wind is guided to the opening 36 through the vertical groove 35 and taken into the inside of the base body cover 31 . The front edge of the opening 36 is located inside the rear edge in the left-right direction, and the rear edge of the opening 36 is formed with a wall surface 39 (see FIG. 8) having a large left-right width. When the running wind hits the wall surface 39 at the rear edge of the opening 36 from the front, the running wind is taken inside the base body cover 31 through the opening 36 .

A lower front surface 41 is formed in such a manner that the front surface of the lower half portion 33 is wider than the front surface of the upper half portion 32 in the left-right direction when viewed from the front. The lower front surface 41 is formed by a front portion facing the front and a slope portion facing obliquely forward. The lower front surface 41 is recessed below the step surface 34, and protrudes forward from the recess 42 toward the front edge of the step surface 34 (see FIG. 3 in particular). Since the slope from the lower front surface 41 to the stepped surface 34 is steep, even if the running wind blows on the muddy water received by the lower front surface 41, it is difficult for the muddy water to get over the front edge of the stepped surface 34.例文帳に追加

A lower outer surface 43 of the base body cover 31 below the stepped surface 34 protrudes laterally outward toward the side edge of the stepped surface 34 (see FIG. 4 in particular). Even if the running wind blows on the muddy water adhering to the lower outer surface 43, the muddy water does not easily get over the side edge of the stepped surface 34.例文帳に追加In the front part of the base body cover 31, the front edge and the side edge of the stepped surface 34 protrude outward, making it difficult for muddy water to flow upward from the stepped surface 34, thereby suppressing muddy water from adhering to the occupant. The lower half portion 33 of the base body cover 31 partially overlaps the rear portion of the front wheel 22 when viewed from the side. A shielding plate 44 (see FIG. 8) protrudes from the inner surface of the lower half portion 33 toward the main frame 12 . Due to this shielding plate 44, even if water or mud enters the inside of the opening 36, it will be difficult for it to enter the inside of the vehicle such as the suction port of an air cleaner (not shown) on the rear upper side.

Above the elongated hole 37 and the projecting portion 38 of the base body cover 31, the outer surface of the upper half portion 32 bulges outward in the left-right direction to form a bulging portion 45. As shown in FIG. The bulging portion 45 extends obliquely upward rearward from the front edge of the base body cover 31, and has a plurality of openings formed therein. A lateral groove 46 is formed in the upper edge of the upper half portion 32 so that the outer surface of the upper half portion 32 is recessed inward in the left-right direction and along the bulging portion 45 . An upper body cover 61 is attached to the outer surface of the bulging portion 45 . The upper body cover 61 extends obliquely upward rearward from the front edge of the base body cover 31 so as to cover the entire bulging portion 45 from the outside.

The outer body cover 51 is attached to the outside of the base body cover 31 below the upper body cover 61 . The outer body cover 51 is formed with an eave-like plate-like portion 52 that covers the stepped surface 34 of the base body cover 31 from above, and a rear cover portion 54 that continues behind the plate-like portion 52 via a connecting portion 53 . The plate-like portion 52 is attached to the elongated hole 37 of the base body cover 31 and extends forward and backward above the step surface 34 . The front edge of the plate-like portion 52 is positioned forward of the front edge of the stepped surface 34, and the muddy water splashed up by the front wheel 22 is received in a wide range by the eave-like plate-like portion 52.例文帳に追加

The plate-like portion 52 slopes downward outward in the left-right direction from the outer surface of the base body cover 31 , and a downwardly bent return portion 55 is formed on the outer side edge in the left-right direction of the plate-like portion 52 . A gap is provided between the inner surface of the return portion 55 and the laterally outer side edge of the step surface 34, and the return portion 55 extends below the side edge of the step surface 34 (see FIG. 4 in particular). The muddy water received by the plate-like part 52 easily flows down from the return part 55 to the lower part of the stepped surface 34, and the muddy water is less likely to go upward than the plate-like part 52, thereby suppressing adhesion of the muddy water to the occupant. Although the return portion 55 is formed in the front half portion of the plate-like portion 52 , the return portion 55 may be formed entirely along the longitudinal direction of the plate-like portion 52 .

The stepped surface 34 and the eave-like plate-like portion 52 form a path for running wind. The front edge of the stepped surface 34 and the front edge of the plate-like portion 52 form an entrance of the running wind, and the running wind enters the entrance of the running wind from the front. As described above, there is a gap between the inner surface of the return portion 55 and the stepped surface 34, and the running wind enters the gap. These running winds are rectified inside the plate-like portion 52 to reduce the running resistance due to the running winds. In this manner, the step surface 34 and the plate-like portion 52 not only receive muddy water splashed up from the front wheel 22, but also form a path for running wind that can reduce running resistance in the body cover 30.例文帳に追加

A rear portion of the plate-like portion 52 is positioned above the longitudinal groove 35 , and a connecting portion 53 is provided at the rear portion of the plate-like portion 52 . The connecting portion 53 is formed with an inner wall surface (guide surface) 56 (see FIG. 7) inclined inward in the left-right direction toward the rear. Wind is directed to the flutes 35 . A rear cover portion 54 is provided below the connecting portion 53 . The rear cover portion 54 covers the outside of the base body cover 31 by extending in the front-rear and up-and-down directions. A portion of the rear cover portion 54 overlaps the vertical grooves 35 and the openings 36 in a side view.

The inner body cover 65 is attached inside the base body cover 31 along the front edge of the base body cover 31 . A lower portion of the inner body cover 65 is formed along the lower front surface 41 of the base body cover 31 . The lower part of the inner body cover 65 is sloped obliquely forward, and receives water droplets from the front together with the lower front surface 41 of the base body cover 31 . The fixing method of the base body cover 31, the inner body cover 65, the outer body cover 51, and the upper body cover 61 is not particularly limited.

With reference to FIGS. 5 to 8, the mud guard structure of the body cover and the airflow path will be described. FIG. 5 is a partially cut side view of the body cover of this embodiment. FIG. 6 is a cross-sectional view of the body cover of FIG. 2 taken along line AA. FIG. 7 is a cross-sectional view of the body cover of FIG. 2 taken along line BB. FIG. 8 is a sectional view of the body cover of FIG. 2 taken along line CC.

As shown in FIG. 5 , the lower front surface 41 of the base body cover 31 is positioned behind the front wheel 22 . Therefore, when the muddy water D is splashed up by the front wheels 22 , the muddy water D is received by the lower front surface 41 of the base body cover 31 . A depression 42 is formed in the lower front surface 41 below the stepped surface 34 , and the lower front surface 41 protrudes forward from the depression 42 toward the front edge of the stepped surface 34 . Therefore, even if the running wind indicated by the arrow F1 is blown against the muddy water D received by the lower front surface 41, it is difficult for the muddy water D to go upward over the front edge of the stepped surface 34.例文帳に追加Even if the muddy water D gets over the front edge of the stepped surface 34, the muddy water D is received by the eaves-like plate-like part 52 above the stepped surface 34.例文帳に追加

As shown in FIG. 6 , the muddy water D splashed up by the front wheel 22 is received by the lower outer surface 43 of the base body cover 31 . The lower outer surface 43 protrudes laterally outward toward the side edge of the stepped surface 34 . Therefore, as shown by arrow F2, even if the running wind blows on the muddy water D received by the lower outer surface 43, it is difficult for the muddy water D to climb over the side edge of the stepped surface 34 and go upward. Even if the muddy water D gets over the side edge of the step surface 34, the muddy water D is received by the eaves-like plate-like part 52 above the step surface 34.例文帳に追加In this way, the muddy water D is prevented from splashing above the plate-like portion 52 and adhering to the occupant.

The plate-like portion 52 is inclined downward toward the left-right direction outer side, and a turn portion 55 is formed on the left-right direction outer side edge of the plate-like portion 52 . Since the plate-like portion 52 is inclined, the muddy water D does not remain on the inner surface of the plate-like portion 52 and easily flows. As indicated by arrow F3, the muddy water D received by the plate-like portion 52 flows down along the inner surface of the return portion 55. As shown in FIG. Since the return part 55 faces downward, the muddy water D flowing down from the return part 55 does not scatter upward. Further, since the lower end of the return portion 55 is located below the stepped surface 34 , the muddy water D is less likely to enter the stepped surface 34 from the return portion 55 .

As shown in FIG. 5 , the stepped surface 34 of the base body cover 31 and the plate-like portion 52 of the outer body cover 51 form a path for running wind. As indicated by an arrow F4, when the wind blows against the body cover 30 from the front, the wind flows rearward between the step surface 34 and the plate-shaped portion 52. As shown in FIG. Further, as indicated by an arrow F5, the running wind also enters through the gap between the side edge of the stepped surface 34 and the return portion 55, and flows rearward between the plate-like portions 52 of the stepped surface 34. In this way, the running wind entering between the stepped surface 34 and the plate-shaped portion 52 from the front and sides is rectified rearward to reduce the running resistance.

As shown in FIG. 7, the outer lateral edge of the step surface 34 is recessed to form a vertical groove 35 extending downward from the step surface 34 toward the opening 36 (see FIG. 5). . An inner wall surface 56 of the connecting portion 53 is positioned outside the longitudinal groove 35 in the left-right direction. The inner wall surface 56 of the connecting portion 53 faces the outer surface of the upper half portion 32 of the base body cover 31, and the inner wall surface 56 of the connecting portion 53 is inclined so that the facing distance narrows rearward. As shown by arrow F6, the running wind flows rearward between the stepped surface 34 and the plate-shaped portion 52 and hits the inner wall surface 56 of the connecting portion 53, and the inclination of the inner wall surface 56 directs the running wind toward the vertical grooves 35. guided.

As shown in FIG. 8, an opening 36 is formed in the base body cover 31 below the step surface 34, and the inner side and the outer side of the base body cover 31 are connected through the opening 36. As shown in FIG. The upper end of the vertical groove 35 continues to the stepped surface 34 and the lower end of the vertical groove 35 extends to the opening 36 . Further, the vertical groove 35 and the opening 36 are partially covered from the outside in the left-right direction by the rear cover portion 54 . As indicated by an arrow F7, when the running wind enters the vertical groove 35, the running wind enters the opening 36 through the space between the vertical groove 35 and the rear cover portion . A wall surface 39 having a large lateral width is formed at the rear edge of the opening 36 , and the running wind from the front hits the wall surface 39 and enters the opening 36 .

In this way, the body cover 30 is formed with a passageway for running wind, and the running wind is efficiently taken into the inside of the base body cover 31 through the opening 36 . The traveling resistance of the body cover 30 is reduced by the path of the traveling wind, and the traveling wind taken inside the base body cover 31 suppresses the diffusion of the hot air from the radiator 24 toward the legs of the occupant. As described above, it is difficult for the muddy water D to enter the stepped surface 34 , so that the muddy water D is prevented from being led to the inside of the base body cover 31 . Intrusion of the muddy water D into the inside of the base body cover 31 is suppressed, and the running wind is taken into the inside of the base body cover 31.例文帳に追加

As described above, according to the present embodiment, even if the muddy water D is splashed by the front wheel 22 and splashed above the step surface 34, the muddy water D is received by the eaves-shaped plate-like portion 52 of the outer body cover 51. be done. Therefore, adhesion of the muddy water D to the occupant of the straddle-type vehicle 1 is suppressed. The stepped surface 34 and the eaves-like plate-like portion 52 form a passageway for the traveling wind, and the traveling wind entering between the stepped surface 34 and the plate-like portion 52 is straightened rearward. Therefore, the running resistance of the straddle-type vehicle 1 due to running wind is reduced. Therefore, it is possible to reduce running resistance while suppressing adhesion of muddy water to the occupant.

Although the body cover includes the base body cover, the upper body cover, the outer body cover, and the inner body cover in this embodiment, the body cover may include at least the base body cover and the outer body cover.

Further, in this embodiment, the side edges of the plate-like portion are positioned laterally outside the side edges of the step surface, but the side edges of the plate-like portion are positioned laterally inside the side edges of the step surface. You may have Moreover, although the front edge of the plate-like portion is positioned forward of the front edge of the step surface, the front edge of the plate-like portion may be positioned rearward of the front edge of the step surface. In other words, the plate-like portion does not need to cover the entire stepped surface, and may cover at least a portion of the stepped surface.

Further, in the present embodiment, the side edges of the plate-like portion are bent downward to form the bent portion, but the side edges of the plate-like portion may be formed straight.

Further, in this embodiment, the plate-like portion and the rear cover portion are connected by the connecting portion, but the plate-like portion and the rear cover portion may be formed separately.

In this embodiment, the lower front surface of the base body cover is formed with a recess, but the lower front surface of the base body cover is not formed with a recess, and the lower front surface protrudes forward toward the front edge of the stepped surface. may

The straddle-type vehicle is not limited to vehicles in general in which the occupant sits astride the seat, but also includes small scooter-type vehicles in which the occupant does not sit astride the seat.

As described above, the body cover (30) of the present embodiment is a body cover for a straddle-type vehicle (1) in which the front wheels (22) are supported on the front part of the body frame (10). and an outer body cover (51) attached to the outside of the base body cover. A stepped surface (34) is formed so as to protrude outward, and the outer body cover is formed with an eave-like plate-like portion (52) so as to cover the stepped surface from above. According to this configuration, even if muddy water is splashed up by the front wheel and splashed above the step surface, the muddy water is received by the eaves-like plate-like portion of the outer body cover. Therefore, muddy water is prevented from adhering to the occupant of the straddle-type vehicle. Further, the stepped surface and the eaves-like plate-like portion form a path for running wind, and the running wind entering between the stepped surface and the plate-like portion is straightened rearward. Therefore, the running resistance of the straddle-type vehicle due to running wind is reduced. Therefore, it is possible to reduce running resistance while suppressing adhesion of muddy water to the occupant.

In the body cover of this embodiment, the front edge of the plate-like portion is located forward of the front edge of the step surface. According to this configuration, muddy water is received by the plate-shaped portion in a wider range, and adhesion of water droplets to the occupant is suppressed.

In the body cover of this embodiment, a downwardly bent return portion (55) is formed on the laterally outer side edge of the plate-like portion. According to this configuration, the muddy water received by the plate-like portion tends to flow down from the return portion, and the muddy water is less likely to flow upwards from the plate-like portion, thereby suppressing adhesion of the muddy water to the occupant.

In the body cover of this embodiment, the return portion extends below the laterally outer side edge of the stepped surface. According to this configuration, the muddy water received by the plate-like portion easily flows down from the return portion to the lower side of the stepped surface, and the muddy water is less likely to flow upwards from the plate-like portion, thereby suppressing muddy water from adhering to the occupant.

In the body cover of this embodiment, the base body cover has an opening (36) formed below the stepped surface and a vertical groove (35) extending from the stepped surface to the opening, and the outer body cover has: A guide surface (inner wall surface 56) is formed to guide the running wind passing inside the plate-like portion to the longitudinal groove. According to this configuration, running wind entering between the stepped surface and the plate-like portion from the front and sides is guided to the opening through the longitudinal groove. Running wind is efficiently taken into the inside of the base body cover.

In the body cover of this embodiment, the outer body cover is formed with a rear cover portion (54) that continues to the rear of the plate-like portion, and a part of the rear cover portion overlaps the vertical groove and the opening when viewed from the side. According to this configuration, the longitudinal groove and the opening are partially covered from the sides by a part of the rear cover portion, and the running wind is efficiently taken into the inside of the base body cover.

In the body cover of this embodiment, the base body cover has a lower front surface (41) formed in such a manner that the lower side of the stepped surface is wider than the upper side in the left-right direction when viewed from the front. According to this configuration, muddy water splashed up by the front wheels is received by the lower front surface, making it more difficult for the muddy water to flow rearward than the lower front surface, thereby suppressing muddy water from adhering to the occupant. In addition, the lateral width above the step surface is narrowed to reduce running resistance.

In the body cover of this embodiment, the lower front surface protrudes forward toward the front edge of the step surface. According to this configuration, even if the running wind is blown onto the muddy water received by the front surface of the lower portion, the muddy water is less likely to climb over the stepped surface, and adhesion of the muddy water to the occupant is suppressed.

In the body cover of this embodiment, the lower front surface is recessed below the step surface, and the lower front surface protrudes forward from the recess (42) toward the front edge of the step surface. According to this configuration, since the slope from the lower front surface toward the stepped surface becomes steep, even if the running wind blows on the muddy water, it becomes difficult for the muddy water to climb over the stepped surface, and adhesion of the muddy water to the occupant is suppressed.

In the body cover of the present embodiment, the lower outer surface (43) below the stepped surface of the base body cover protrudes laterally outward toward the side edge of the stepped surface. According to this configuration, even if the running wind blows on the muddy water on the lower outer surface, it becomes difficult for the muddy water to climb over the stepped surface, and adhesion of the muddy water to the occupant is suppressed.

Although the present embodiment has been described, another embodiment may be a combination of the above embodiments and modifications in whole or in part.

Also, the technology of the present invention is not limited to the above-described embodiments, and may be variously changed, replaced, and modified without departing from the spirit of the technical idea.
