Description

  The present invention relates to a clip mounting structure for a molded product, and more particularly to a clip mounting structure used for mounting a car interior / exterior component to a vehicle body panel.

  Generally, a clip mounting structure is widely used when assembling a molded article. In particular, when an automobile interior part is attached to a vehicle body panel, a clip formed separately is held on a clip attachment seat formed on the interior part, and is fitted into an attachment hole of the vehicle body panel. (For example, see Patent Document 1).

FIG. 11 shows the clip mounting structure of Patent Document 1. As shown in FIG. 11, the clip mounting structure of Patent Document 1 has a flat plate-like rising plate portion 10 that stands up from the panel surface of the interior component R, and a predetermined surface of the interior component R from the protruding end side of the rising plate portion 10. The clip seating part 11 and the both side board parts 12 and 13 which protrude in a substantially parallel direction with the space | interval of a vehicle body panel are comprised. The clip seating portion 11 includes a keyhole-like clip attachment hole 14 that is open at one end, and the clip is inserted into the attachment hole 14 along the horizontal direction with the vehicle body panel and engaged with the clip seating portion 11.

  In the clip mounting structure as in Patent Document 1, a slide core is required for the mold when forming the clip seating portion 11 including the released keyhole-shaped clip mounting hole 14, which increases the cost of the mold. As a result, the number of molding steps increases. Further, when the clip is inserted into and engaged with the clip seating portion 11, it is necessary to move the clip horizontally along the vehicle body panel along the horizontal direction and insert it into the attachment hole 14. On the other hand, the efficiency of the installation work is reduced. Further, since the attachment hole 14 has an open keyhole shape, the clip once attached may escape from the release end again by an external force, and the mechanical strength and reliability of the clip attachment structure are sufficient. Absent.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a clip mounting structure that is easy to mount and has high mechanical strength.

Since the first cylindrical member, the second cylindrical member, and the supporter are attached by being press-fitted to the molded product body vertically and coaxially in order, the mounting operation is simplified and the mounting efficiency is improved. . In addition, when forming the clip mounting structure of the present invention, the need for a slide core in the mold is eliminated, the cost of the mold can be suppressed, and the number of molding steps can be reduced.

  (2) It is preferable that the said 2nd cylindrical member of the clip attachment structure of this invention is comprised with the material which has hardness higher than a said 1st cylindrical member.

  Thereby, the tooth | gear part of a 2nd cylindrical member becomes easy to bite into a 1st cylindrical member, and can be attached more reliably.

  (3) It is preferable that the said 2nd cylindrical member of the clip attachment structure of this invention consists of a several isolation | separation body which can adjoin and can space in the circumferential direction.

  Thereby, the some isolation | separation body which comprises a 2nd cylindrical member can adjoin and space apart in the circumferential direction. That is, when the second cylindrical member is press-fitted into the first cylindrical member, the second cylindrical member can be reduced in diameter by the relative movement (proximity) of the separator, and the first cylindrical member can be easily reduced. Can be inserted inside. Further, when the supporter is press-fitted into the second cylindrical member, the diameter of the second cylindrical member can be increased by relative movement (separation) of the separator, and the supporter can be easily inserted. Therefore, the clip can be securely attached to the molded product body at the same time as the work of attaching is simplified. In the present invention, “proximity” means that the separated bodies approach each other. Further, “separation” means separation of the separated bodies. When the separators are close to each other, the diameter of the second cylindrical member is reduced (reduced). Moreover, when the separated bodies are separated from each other, the diameter of the second cylindrical member is increased (expanded).

  (4) The supporter of the clip mounting structure of the present invention includes a head having an outer diameter larger than the outer diameter of the rod-shaped portion at the tip of the rod-shaped portion, and the head is formed of the second cylindrical member.

It is preferable that the cylindrical member abuts on the tooth portion and is engaged with the tooth portion by biting deformation.

  Thereby, the tooth | gear part formed in the outer peripheral surface of a 2nd cylindrical member can engage with the protrusion part formed in the inner surface of a 1st cylindrical member. Therefore, the engagement between the first tubular member and the second tubular member is further enhanced, and as a result, the clip can be attached to the formed product body more stably and reliably.

  (10) It is preferable that the other end of the supporter of the clip mounting structure of the present invention is provided with an engaging portion that engages and holds the clip with the supporter so as to be relatively movable.

  As a result, the mounting position of the clip mounting structure can be adjusted, and the work of attaching interior parts to the vehicle body panel becomes easier.

  (11) The clip mounting structure of the present invention is preferably used for interior and exterior parts of an automobile.

  According to the clip mounting structure of the present invention, a keyhole-shaped clip mounting hole in the molded product body is unnecessary, so that a slide core is not necessary for the mold, and the molding cost including the mold cost can be reduced. Further, the clip mounting structure of the present invention can mount the clip to the molded product main body stably and reliably while realizing high mechanical strength. Furthermore, by integrally forming the components coaxially, the attachment of the clip can be completed by one push (one push operation), the attachment operation is simplified, and the attachment efficiency is improved.

  The clip mounting structure of the present embodiment includes a first cylindrical member, a second cylindrical member, a supporter, and a clip.

  The first tubular member has a cylindrical shape and is formed integrally with the molded product body. In addition to the cylindrical shape, for example, a triangular shape or the like may be used.

  The first cylindrical member is formed so as to protrude vertically from the surface of the molded product body. In addition, in consideration of mechanical strength etc., the formation angle etc. of a 1st cylindrical member can be adjusted. That is, the first tubular member can be formed so as to protrude in a direction other than the vertical direction with respect to the surface of the molded product body.

  The first tubular member has an opening at one end. From this opening, the second cylindrical member is press-fitted into the first cylindrical member.

  The second tubular member has openings at both ends. Moreover, a tooth part is formed in a substantially ring shape along the outer peripheral direction on the outer peripheral surface of the second cylindrical member.

  It is desirable that the tooth portion has a diameter that increases from the front end side toward the rear end side and is formed in a saw blade shape in cross section. Thereby, a tooth | gear part becomes easy to bite into a 1st cylindrical member, and a 2nd cylindrical member can be fixed to a 1st cylindrical member effectively. Therefore, the clip can be attached to the molded product body stably and reliably.

  Moreover, it is desirable that the second cylindrical member is made of a material having a higher hardness than the first cylindrical member. Examples of the material constituting the first tubular member include PP resin. Moreover, POM resin etc. can be illustrated as a material which comprises a 2nd cylindrical member.

  As a result, the tooth portion of the second cylindrical member can easily bite into the first cylindrical member, can be attached more reliably, and is advantageous in improving mechanical strength and the like.

  Moreover, it is desirable that the second cylindrical member is formed from a plurality of separated bodies that can be moved toward and away from each other in the circumferential direction. In the present embodiment, slits are formed between the separated bodies, and the separated bodies can move relative to each other to change the diameter of the second cylindrical member. Thus, when the second cylindrical member is press-fitted into the first cylindrical member, the second cylindrical member can be reduced in diameter by the relative movement (proximity) of the separator, and the first cylindrical member can be easily reduced. Can be inserted inside. Further, when the supporter is press-fitted into the second cylindrical member, the second cylindrical member can be enlarged in diameter by the relative movement (separation) of the separator, and the supporter can be easily inserted. Therefore, the work of attaching the clip can be simplified, and at the same time, the clip can be reliably attached to the formed product body. In addition to the method of forming a slit between the separated bodies and reducing the diameter and expanding the diameter by “adjacent” or “separated”, the separated body is made of an elastic member that can be deformed according to an external force. There is also a method in which a part of the second cylindrical member is formed by reducing the elastic member and reducing the diameter and the diameter of the second cylindrical member.

  The supporter includes a rod-shaped portion at one end, and the rod-shaped portion has an outer diameter larger than the inner diameter of the second cylindrical member. A clip is engaged and held at the other end of the supporter.

  Moreover, a head can be provided at the tip of the rod-shaped portion. The head has an outer diameter that is larger than the outer diameter of the rod-shaped portion. The head portion press-fitted into the second cylindrical member simultaneously with the rod-shaped portion passes through the second cylindrical member and then protrudes from the opening at the other end of the second cylindrical member. Engage with the other end face. Since the rod-shaped portion is provided with a head, the supporter fixedly held inside the second cylindrical member by frictional resistance is further engaged with the opening (the other end surface) at the other end of the second cylindrical member via the head. Combined. Therefore, the clip held at the other end of the supporter can be more reliably engaged and held by the second cylindrical member. As a result, the clip can be attached to the molded product body stably and reliably.

  As described above, the second cylindrical member is press-fitted coaxially from the opening of the first cylindrical member into the first cylindrical member. And a supporter is press-fitted coaxially in the inside of a 2nd cylindrical member from the opening of the end of a 2nd cylindrical member. In addition, by pressing the supporter into the second cylindrical member, the tooth portion of the second cylindrical member expands and bites into the inner peripheral surface of the first cylindrical member, so that the clip is inserted into the molded product body. Retained.

  By setting the clip mounting structure of the present embodiment to such a configuration, the second cylindrical member is press-fitted into the first cylindrical member, and the supporter is press-fitted into the second cylindrical member, so that the tooth portion is Thus, the second cylindrical member is engaged with the first cylindrical member, and the clip held at the other end of the supporter can be securely attached to the molded product body. Further, the second cylindrical member and the supporter are coaxially press-fitted into the first cylindrical member to be integrated, and the clip can be stably and surely attached to the molded product body while realizing high mechanical strength. Since the first cylindrical member, the second cylindrical member, and the supporter are attached by being press-fitted to the molded product body vertically and coaxially in order, the mounting operation is simplified and the mounting efficiency is improved. .

  Moreover, it is desirable that the first tubular member of the clip mounting structure of the present embodiment includes a protruding portion that is formed on at least a part of the inner peripheral surface and protrudes from the inner peripheral surface. Moreover, a protrusion part contacts the tooth | gear part of a 2nd cylindrical member, and is engaged with a tooth | gear part by bite deformation. By providing the protruding portion, the tooth portion formed on the outer peripheral surface of the second cylindrical member is further enhanced in engagement with the inner surface of the first cylindrical member, and the clip is formed more stably and reliably. Can be attached to.

  In addition, it is desirable that guide portions are formed on the first cylindrical member and the second cylindrical member of the clip mounting structure of the present embodiment. The guide portion guides relative movement between the first tubular member and the second tubular member when the second tubular member is press-fitted into the first tubular member. Specifically, the guide includes, for example, a protrusion formed along the axial direction on the inner peripheral surface of the first tubular member, and a groove formed on the outer peripheral surface of the second cylindrical member according to the protrusion. Can consist of The ridge formed on the inner peripheral surface of the first cylindrical member is introduced into the groove formed on the outer peripheral surface of the second cylindrical member, and the second cylindrical member is changed to the first by a combination of the groove and the ridge. It is possible to guide the inside of the cylindrical member. In addition, it is preferable that a guide part is made into the linear form extended in an axial direction.

  By providing the guide portion, the mounting operation of the clip mounting structure of the present embodiment becomes easier, and the mounting efficiency is improved. Further, by forming the guide portion along the axial direction, the relative position between the first cylindrical member and the second cylindrical member can be fixed in the circumferential direction. Thereby, the relative (rotation) movement of the 2nd cylindrical member press-fitted inside the 1st cylindrical member can be suppressed, and the more stable clip attachment structure can be implement | achieved.

  Similarly to the first cylindrical member, the second cylindrical member and the supporter are basically formed in a cylindrical shape (circular sectional shape), but other cylindrical shapes (for example, a triangular cylindrical shape, a sectional shape). Can also be a triangle).

  The second cylindrical member and the supporter are preferably formed by integral molding. In some cases, the second cylindrical member, the supporter, and the clip can be formed by integral molding. A 2nd cylindrical member and a supporter can be integrated via fracture parts, such as a thin part. In addition, the rupture portion breaks during press-fitting. By integrally forming the second cylindrical member, the supporter, and the clip, the clip mounting structure of this embodiment can be easily manufactured and mounted. Further, the number of parts can be reduced, and the number of manufacturing steps can be reduced.

  Moreover, it is desirable that the other end of the supporter be provided with an engaging portion that engages and holds the clip so as to be relatively movable with the supporter. The engaging portion can enable a predetermined relative movement between the clip and the supporter while engaging and holding the clip with the other end of the supporter. Thereby, the mounting position of the clip mounting structure can be adjusted, and the mounting work to the vehicle body panel becomes easier. In addition, in the clip mounting structure, by providing an engaging portion that enables relative movement, it is possible to absorb the fluctuations in the mounting position due to the accuracy of the mounting parts and the position of the mounting holes in the vehicle body panel, and is stable and high. A clip mounting structure that can be easily mounted while having mechanical strength can be realized.

  Further, the clip mounting structure of the present embodiment is preferably used for an interior / exterior part of an automobile.

(First cylindrical member)
As shown in FIG. 3, the first tubular member 10 is formed in a cylindrical shape by vertically projecting from a surface 991 on the back side of a molded product body 99 such as a pillar garnish. The first tubular member 10 has an opening 101 at one end. A side wall 102 is formed between the opening 101 and the molded product main body 99. The side wall portion 102 includes an inner peripheral surface 1021 and an outer peripheral surface 1022. An end face 1011 is formed on the opening 101 side.

  Also, as shown in FIG. 1 or FIG. 2, a plate-like shape that vertically connects the surface 991 and the outer peripheral surface 1022 between the outer peripheral surface 1022 of the first tubular member 10 and the surface 991 of the molded product body 99, respectively. The rib 103 is formed. A plurality of (four) ribs 103 are equally arranged along the circumferential direction of the first tubular member 10.

  The molded product main body 99, the first tubular member 10, and the rib 103 are integrally formed, and the side wall portion 102 is reinforced by the rib 103.

  Further, as shown in FIG. 1, the inner peripheral surface 1021 (see FIG. 2) of the first tubular member 10 protrudes from the inner peripheral surface 1021 and extends along the axial direction, and a guide portion. 105.

  As shown in FIG. 1, a plurality of (four) protrusions 104 are equally formed on the inner peripheral surface 1021. Moreover, the protrusion part 104 can be engaged by biting with the tooth | gear part 203 of the 2nd cylindrical member 20 mentioned later. One protrusion 104 can play the role of “engage”, but in order to support and engage the second tubular member 20 in the first tubular member 10 more stably, the protrusion 104 104 is preferably 3 or more.

A plurality of (four) guide portions 105 are equally formed on the inner peripheral surface 1021. The guide portion 105 is formed on the second cylindrical member 20 and is fitted to a guide mating member 1051 described later, and serves as a guide when the second cylindrical member 20 is inserted into the first cylindrical member 10. To determine the relative position. In the present embodiment, a plurality of guide portions 105 are provided. However, the present invention is not limited to this, and one guide portion 105 may be provided.
(Second cylindrical member)
As shown in FIG. 3, the second cylindrical member 20 includes a substantially cylindrical portion 204 and a flat portion 205. A common inner peripheral surface 2041 is formed inside the substantially cylindrical portion 204 and the flat portion 205. The substantially cylindrical portion 204 is connected to the flat portion 205 via the thin portion 2043.

  As shown in FIG. 3, the second tubular member 20 includes an opening 201 on the substantially tubular portion 204 side and an opening 202 on the flat portion 205 side. An end surface 2011 and a trapezoidal surface 2044 are formed on the opening 201 side. The flat part 205 includes end surfaces 2051 and 2052, respectively. By providing the trapezoidal surface 2044 on the opening 201 side of the second cylindrical member 20, the operation when the second cylindrical member 20 is press-fitted into the first cylindrical member 10 from the opening 101 can be performed more easily.

  The substantially cylindrical portion 204 forms an outer peripheral surface 2042 that connects the trapezoidal surface 2044 and the flat portion 205. Further, the outer peripheral surface 2042 is formed with a tooth portion 203 having a saw-tooth shape in cross section. Further, as can be understood from FIG. 1, the plurality of tooth portions 203 are formed in a ring shape along the outer peripheral direction of the second cylindrical member 20. Further, as shown in FIG. 3, the tooth portion 203 has a saw blade shape with a cross section that increases in warp from the front end side (opening 201 side) to the rear end side (opening 202 side).

  Since the tooth portion 203 has a length increasing from the front end side toward the rear end side, when the second cylindrical member 20 is press-fitted from the opening 101 into the first cylindrical member 10 with the end of the opening 201 as the front end. In addition, the outer peripheral surface 2042 of the second cylindrical member 20 having the tooth portion 203 can be press-fitted while sliding more smoothly on the inner peripheral surface 1021 of the first cylindrical member 10. Further, after the second tubular member 20 is once press-fitted into the first tubular member 10, the second tubular member 20 is unlikely to escape from the first tubular member 10 due to the inclination of the tooth portion 203. .

  FIG. 4 shows a plan view of the second tubular member 20 (viewed in the B direction shown in FIG. 3). As shown in FIG. 4, the substantially cylindrical portion 204 of the second cylindrical member 20 is composed of a plurality (four) of separated bodies 200 having a sector cross section. The four separated bodies 200 are equally arranged in a ring shape, and slits S are formed between the separated bodies 200.

  Note that the slit S constitutes a guide mating member 1051. That is, the guide part 105 formed on the inner peripheral surface 1021 of the first cylindrical member 10 and the mating guide member 1051 (slit S) formed on the substantially cylindrical part 204 of the second cylindrical member 20 are fitted. Due to the relationship, the second tubular member 20 can be easily press-fitted into a predetermined relative position inside the first tubular member 10. Moreover, the relative movement (relative rotation) between the 1st cylindrical member 10 and the 2nd cylindrical member 20 can also be prevented.

  The second cylindrical member 20 is made of a resin (POM resin) having elasticity, and further, since a thin portion 2043 is formed between the separator 200 and the flat portion 205, when an external force is applied, Separator 200 can move within a certain range along the radial direction (swing in the direction of increasing or decreasing the diameter) with opening 201 as the fulcrum.

In addition, as can be understood from FIG. 4, the tooth portion 203 formed on the outer peripheral surface 2042 of the substantially cylindrical portion 204 is arranged in a substantially ring shape. As in the case of the separating body 200, the tooth portion 203 can also move along the radial direction (perpendicularly in the direction of increasing or decreasing the diameter).
(Supporter)
As shown in FIG. 3, the supporter 30 includes a rod-shaped portion 301 formed at one end and a flat portion 302 formed integrally with the rod-shaped portion 301 at the other end. The rod-shaped portion 301 includes a distal end portion 303 formed in a substantially conical shape at the distal end and an outer peripheral surface 3011. A flat portion 302 formed at the other end of the supporter 30 includes end surfaces 3021 and 3022. Further, the clip 40 is integrally formed on the end surface 3022 and is engaged with and held by the supporter 30.

  Further, a connecting portion L for integral molding is formed between the tip portion 303 of the supporter 30 and the opening 202 of the second cylindrical member 20. That is, the second cylindrical member 20 and the supporter 30 are integrally formed through the connecting portion L. Moreover, the connection part L is formed so that it can be cut | disconnected easily, when attaching.

Further, as can be understood from FIG. 3, an engaging portion 304 is formed on the end surface 3022 of the flat portion 302 formed at the other end of the supporter 30. The engaging portion 304 includes two plate-shaped members 3041 having the same shape that are orthogonal to the end surface 3022 and parallel to each other. At the center of these two plate-like members 3041, a through hole (engagement port) 3042 is provided. Further, an engagement space 3043 is formed between the plate-like members 3041.
(clip)
As shown in FIG. 3, the clip 40 includes a clip body 401, a plate-like connecting member 402 extending in the axial direction, and an engagement counterpart 403 that is formed at one end of the plate-like connecting member 402 and is orthogonal to the plate-like connecting member 402. And. In other words, the clip body 401 is connected to the engaging counterpart 403 via the plate-like connecting member 402.

  Further, the engagement counterpart 403 is inserted into the engagement space 3043 through the plate-like connecting member 402 and further inserted into the engagement port 3042 of the plate-like member 3041. That is, in the engagement space 3043, the clip 40 and the supporter 30 are integrally formed so that the mating counterpart 403 does not escape from the engagement port 3042 even if the plate-like connecting member 402 moves. For this reason, the clip 40 is engaged and held so as to be movable relative to the supporter 30.

  Next, the attachment procedure (method) of the clip attachment structure of the present embodiment will be described.

  (1) The second cylindrical member 20 is press-fitted into the first cylindrical member 10.

  FIG. 5 shows a state in which the second tubular member 20 is press-fitted into the first tubular member 10 of the clip mounting structure of the present embodiment. As shown in FIG. 5, the opening 201 side of the second tubular member 20 is coaxially inserted from the opening 101 of the first tubular member 10 integrally formed on the surface 991 of the formed article main body 99.

  At this time, as shown in FIG. 1, the second tubular member 20 is more easily press-fitted into the first tubular member 10 by combining the guide portion 105 and the guide mating member 1051 (slip S). be able to. Moreover, the relative position in the circumferential direction of the second cylindrical member 20 and the first cylindrical member 10 can be fixed (locked).

  By pressing the second tubular member 20 against the first tubular member 10 side, the tooth portion 203 of the second tubular member 20 is in sliding contact with the inner peripheral surface 1021 of the first tubular member 10, and thus the second tubular member 20. The member 20 is press-fitted coaxially into the first cylindrical member 10. The end surface 2051 of the flat portion 205 of the second cylindrical member 20 comes into contact with the end surface 1011 of the first cylindrical member 10 and stops.

  Since the outer diameter R21 (see FIG. 3) of the second cylindrical member 20 is set larger than the inner diameter R1 (see FIG. 3) of the first cylindrical member 10, the second cylindrical member 20 is When pressed into the inside of the one cylindrical member 10, the plurality of separators 200 (see FIG. 4) constituting the substantially cylindrical portion 204 of the second cylindrical member 20 are restricted by the regulating force of the first cylindrical member 10. As a result, the gap between the slits S (see FIG. 4) is reduced, and the slit S (see FIG. 4) is deformed (inclined) from the opening 202 side to the opening 201 side. That is, by providing the thin portion 2043 formed between the separating body 200 and the flat portion 205 and the slit S formed between the separating bodies 200, external force (the first cylindrical member 10 on the side to be inserted) is provided. The separating member 200 can be moved in the radial direction by the control force of the above.

  (2) The supporter 30 is further press-fitted into the second cylindrical member 20.

  FIG. 6 shows a state in which the supporter 30 is press-fitted into the second cylindrical member 20 of the clip mounting structure of the present embodiment. As shown in FIG. 6, the end portion 303 side of the rod-shaped portion 301 is coaxially inserted from the opening 202 of the second tubular member 20 press-fitted into the first tubular member 10. At this time, the connecting portion L shown in FIG. 5 is broken.

  By pressing the supporter 30 against the second cylindrical member 20, the outer peripheral surface 3011 of the rod-shaped portion 301 is slidably in contact with the inner peripheral surface 2041 of the second cylindrical member 20, and is coaxial with the opening 201 side of the second cylindrical member 20. Press fit. The end surface 3021 of the flat portion 302 of the supporter 30 comes into contact with the end surface 2052 of the second tubular member 20 and stops.

  Since the outer diameter R3 (see FIG. 3) of the rod-shaped portion 301 of the supporter 30 is set larger than the inner diameter R22 (see FIG. 3) of the substantially tubular portion 204 of the second tubular member 20, the rod-shaped portion. When 301 is press-fitted into the second cylindrical member 20, the plurality of separators 200 (see FIG. 4) constituting the substantially cylindrical portion 204 are pressed in the radial direction from the center and expanded in diameter. Transforms into

  Thereby, while the frictional resistance force between the outer peripheral surface 3011 of the rod-shaped portion 301 and the inner peripheral surface 2041 of the second cylindrical member 20 is increased, the diameter of the second cylindrical member 20 is increased, so that the substantially cylindrical portion 204 is improved. The teeth 203 formed on the outer peripheral surface 2042 bite into and engage with the protrusions 104 (see FIG. 1) formed on the inner peripheral surface 1021 of the first tubular member 10. Therefore, the engagement between the first tubular member 10 and the second tubular member 20 is further enhanced, and the clip 40 can be attached to the formed product body 99 more stably and reliably.

  When the rod-shaped portion 301 of the supporter 30 is press-fitted coaxially into the second cylindrical member 20, the second cylindrical member 20 expands in diameter, and the tooth portion 203 bites into the protruding portion 104 of the first cylindrical member 10. As a result, the supporter 30 is fixed to the first tubular member 10. Therefore, the clip 40 is engaged and held so as to be relatively movable with respect to the first tubular member 10 via the engaging portion 304 formed at the other end (end surface 3022) of the supporter 30. As a result, the clip 40 is stably held by the molded product body 99.

  In the present embodiment, the protrusion 104 is provided on the inner peripheral surface 1021 of the first tubular member 10 to increase the degree of biting with the tooth portion 203 and to strengthen the engagement relationship. Without providing 104, it is also possible to engage the tooth portion 203 directly into the inner peripheral surface 1021.

  Thus, in the clip mounting structure of the present embodiment, the tooth portion 203 is formed by press-fitting the second cylindrical member 20 into the first tubular member 10 and further press-fitting the supporter 30 into the second tubular member 20. Thus, the second tubular member 20 is engaged with the first tubular member 10 and the clip 40 held at the other end of the supporter 30 can be securely attached to the molded product body 99. Further, the second cylindrical member 20 and the supporter 30 are coaxially press-fitted into the first cylindrical member 10 so as to be integrated, and the clip 40 is attached to the molded product body 99 stably and securely while realizing high mechanical strength. Can do. Since the first cylindrical member 10, the second cylindrical member 20, and the supporter 30 are attached by being press-fitted in the vertical direction and coaxially in order with respect to the molded product main body 99, the mounting operation is simplified. , Mounting efficiency is improved. In addition, by providing the engaging portion 304 on the supporter 30, a change in the relative position between the clip 40 side and the mounting hole of the vehicle body panel is absorbed, and the mounting operation is further simplified.

  Further, since the second cylindrical member 20, the supporter 30 and the clip 40 are formed coaxially and integrally, when being attached, the clip is attached to the molded product main body 99 by one push (press-fit only once) along the axial direction. 40 can be attached. Therefore, it is possible to realize a convenient clip mounting structure that is easy to manufacture and mount.

  In addition, the clip mounting structure of this embodiment is mainly used for mounting an interior / exterior part of an automobile, but can also be used for general mounting operations.

  Further, in the clip mounting structure of the present embodiment, the molded product main body 99 and the first cylindrical member 10 are integrally formed using PP resin. At this time, the slide core is unnecessary, the cost of the mold can be reduced, and the manufacturing cost can be suppressed.

  The 2nd cylindrical member 20, the supporter 30, and the clip 40 are integrally formed using POM resin.

  Thus, the clip mounting structure of the present embodiment can reduce the number of molding steps and can further reduce the manufacturing cost by integrally forming the parts.

  The POM resin that constitutes the second cylindrical member 20 has a higher hardness than the PP resin that constitutes the first cylindrical member 10. For this reason, the tooth part 203 of the 2nd cylindrical member 20 becomes easy to bite into the 1st cylindrical member 10 (projection part 104), and can attach the clip 40 to the molded article main body 99 side more reliably.

In addition to the PP resin and POM resin, the clip mounting structure can be manufactured using other resins or metal materials.
