Further, a pin insertion hole 15 penetrating in a substantially vertical direction (arrow a direction) with respect to the bumper holding wall 10c is formed at a substantially central portion of the bumper holding wall 10c. The pin insertion hole 15 has a substantially circular shape centered at a substantially central portion of the bumper holding wall 10c and having a predetermined diameter d. Further, a pair of cutout portions 16, 16 cut out toward the outside in the diameter direction of the pin insertion hole 15 is formed. The notches 16, 16 are paired in a diameter direction substantially parallel to the longitudinal direction of the bumper holding wall 10 c, and have a substantially rectangular shape that is cut out by a predetermined length l toward the outside. Also, pin insertion holes 20 and 21 (see FIG. 4) having substantially the same shape as the pin insertion hole 15 and having a notch not shown in the diameter direction are formed in substantially the center of each wall. The pin insertion holes and the notches are formed or formed so that their shapes and positions overlap when the resin clip is viewed from the front. And the pin 1 mentioned later is inserted in each pin insertion hole and a notch part toward an insertion direction (arrow a direction).
[0012]
Further, as shown in FIG. 4, a substantially cylindrical pin is provided at a substantially central portion of the side surface 10e1 in the direction of arrow a of the fender liner holding wall 10e so as to surround a pin insertion hole 21 formed in the fender liner holding wall 10e. A holding part 18 is projected. In a region surrounded by the pin holding portion 18, a seating surface 19 is formed on which a locking surface 2 b of a locking projection 2 provided on the pin 1 described later is engaged. The seating surfaces 19 are paired in a direction substantially perpendicular to the diameter direction in which the notches 16 are formed, and the pin 1 is inserted into each pin insertion hole, and then the locking projection 2 The engaging surface 2 b is engaged with the seating surface 19, so that it can be attached to the resin clip 10.
[0013]
Next, the structure of the pin 1 will be described with reference to FIGS. As shown in FIGS. 1 and 2, the pin 1 is integrally formed of a synthetic resin material, and is provided with a substantially cylindrical body 1a and one end of the body 1a. And a substantially disc-shaped head 1b formed on the same axis. Further, a pair of locking projections 2 and 2 project from the outer side surface 1a1 of the body portion 1a near the end in the direction of arrow a, which is the insertion direction of the pin 1, toward the outer side in the diameter direction. The locking protrusions 2 and 2 each have a slope 2a inclined toward the axis n toward the direction of arrow a and a locking surface 2b substantially perpendicular to the axis n, and are substantially perpendicular to the front view. It has a triangular shape.
[0014]
Further, a slit S that is long in the axial center n direction and penetrates in a direction substantially perpendicular to the protruding direction of the locking projections 2 and 2 is formed inside the locking projections 2 and 2. The protrusions 2 and 2 can be bent toward the axis n by the slits S so that each inclined surface 2a receives a force in the direction opposite to the arrow a. Note that the dimension between the outermost protruding portions of the locking projections 2 and 2, that is, the dimension between the positions where the inclined surfaces 2a and the locking surfaces 2b of the opposing locking projections 2 and 2 cross each other, The locking projections 2, 2 are larger than the diameter d of the insertion hole 15. When the pin 1 is inserted into the pin insertion hole 15, the inclined surfaces 2 a, 2 a abut against the peripheral edge 15 a of the pin insertion hole 15. By receiving a force in the direction opposite to the arrow a, the pin insertion hole 15 can be inserted by bending toward the axis n side. In addition, the dimension between the outermost protruding portions of the locking projections 2 and 2 is smaller than the dimension l1 between the ends of notch portions 16 and 16, which will be described later, and the locking projections 2 and 2 are notched portions. 16 and 16 can always be inserted. Further, on the surface 1b1 opposite to the body 1a of the head 1b, a groove 3 into which a tool or the like is fitted to rotate and remove the pin 1 inserted into the resin clip 10 extends in the diameter direction of the disk. Is formed.
[0015]
A pair of guides 5 and 5 extend radially from the end of the trunk portion 1a on the arrow a direction side in the direction of the arrow a. As shown in FIG. 3, when the pins 1 are viewed from the side, the guides 5 and 5 have an upper bottom on the lower body 1a side and a lower bottom on the opposite side to the upper body 1a in FIG. The left and right central portions of the lower base have a substantially trapezoidal shape that is notched into a substantially U shape by the notch 6 to the vicinity of the upper base. The extending directions of the guides 5 and 5 are substantially perpendicular to the protruding direction of the locking projections 2 and 2, and when the pin 1 is viewed in plan (in the axial center n direction), A cross is formed by the locking projections 2 and 2. Each of the guides 5 and 5 is on the opposite side of the notch 6 and has an inclined surface 7 inclined outward in the direction opposite to the body portion 1a, and extends from the end portion of the inclined surface 7 to the lower bottom side, and has an axial n direction. It has the guide surface 8 which became substantially parallel.
[0016]
Note that the dimension between the guide surfaces 8 and 8 is the maximum dimension l2 between the guides 5 and 5, and the ends of the notches 16 and 16 of the pin insertion hole 15 provided in the resin clip 10 shown in FIG. Since it is substantially the same as the dimension l1 between, the guides 5 and 5 can be inserted through only the notches 16 and 16 in a normal state.
[0017]
The guides 5 and 5 are substantially V-shaped with the notch 6 interposed therebetween, and each of the slopes 7 is bent in the direction of the axis n by receiving the force in the direction of the arrow a. It can be removed. As a result, the guides 5 and 5 can bend in the axis n direction until the slopes 7 and 7 are substantially parallel to the axis n direction, and the dimension 12 between the guide surfaces 8 and 8 is notched. The dimension between the ends of the portions 16 and 16 can be reduced to substantially the same dimension as the diameter d of the pin insertion hole 15. Therefore, the guides 5 and 5 can be inserted through the pin insertion hole 15 in a state where the guides 5 and 5 are bent to the maximum in the direction of the axis n.
[0018]
Next, a method for attaching the pin 1 to the resin clip 10 holding the bumper 45 and the fender liner 46 will be described with reference to FIG. As shown in FIG. 4, with the bumper 45 and the fender liner 46 inserted into the bumper holding portion 13 and the fender liner holding portion 14 of the resin clip 10, the body portion 1 a of the pin 1 is connected to the resin clip 10. A pin insertion hole 15 formed in the bumper holding wall 10c, a pin insertion hole 20 formed in the intermediate wall 10a, and a pin insertion hole 21 formed in the fender liner holding wall 10e. Will be inserted.
[0019]
The pin 1 has the guides 5 and 5 extending in the direction parallel to the diameter direction in which the notches 16 and 16 of the bumper holding wall 10c are formed, and the guides 5 and 5 are inserted into the notches 16 and 16, Then, it is pushed toward the insertion direction (arrow a direction). The guides 5 and 5 can be inserted through the notches 16 and 16 as they are, and the notches formed in the intermediate wall 10a and the fender liner holding wall 10e can be inserted as they are. Further, the inclined surface 2a of the locking projections 2 and 2 is caught by the peripheral edge portion 15a of the pin insertion hole 15, and when the pin 1 is further pushed in the direction of arrow a, the inclined surfaces 2a and 2a are respectively inserted into the pin insertion hole. 15 is in contact with the peripheral edge portion 15a and receives a force in the direction opposite to the arrow a and bends in the direction of the axis n, so that the locking projections 2 and 2 can be inserted through the pin insertion hole 15. Similarly, the locking protrusions 2 and 2 are formed in the pin insertion hole 20 formed in the intermediate wall 10a and the fender liner holding wall 10e while the locking protrusions 2 and 2 are bent in the axial center n direction. The pin insertion hole 21 is inserted. Then, the locking surface 2b of the locking projection 2 is seated and locked on the seating surface 19 formed in the area surrounded by the pin holding portion 18 on the side surface 10e1 in the arrow a direction of the fender liner holding wall 10e. Thus, the pin 1 is attached to the resin clip 10 and the bumper and fender liner holding portions 13 and 14 are prevented from opening.
[0020]
Further, as shown in FIG. 5, in order to remove the pin 1 from the resin clip 10, first, a tool or the like (not shown) is fitted into the groove 3 formed in the head 1b of the pin 1, and the tool is rotated. Then, the pin 1 is rotated 90 degrees toward the front or back in the figure. Due to the rotation, the locking projections 2 and 2 are detached from the seating surface 19 and fit in the notches 16 and 16. In this state, when the pin 1 is pulled in the pulling direction (the direction opposite to the arrow a), the guides 5 and 5 of the pin 1 are formed in the pin insertion holes 21 in which the inclined surfaces 7 and 7 are formed in the fender liner holding wall 10e. By abutting the peripheral edge and receiving a force in the direction of arrow a, it bends in the direction of the axis n. Since the guides 5 and 5 can be inserted through the pin insertion holes formed in the respective wall portions in a state where the guides 5 and 5 are bent to the maximum in the direction of the axis n, by pulling the pin 1 in the direction opposite to the arrow a, The pin 1 can be easily extracted from the resin clip 10.
[0021]
As described above, in the pin structure of the resin clip of the present embodiment, the pin 1 attached to the resin clip 10 includes the locking protrusions 2 and 2 protruding from the outer surface of the body portion 1a, and the body portion. 1a includes a pair of guides 5 and 5 extending radially in a direction substantially perpendicular to the projecting direction of the locking projections 2 and 2. The guides 5 and 5 have a shape inclined toward the axis n side of the trunk portion 1a in the direction opposite to the insertion direction (arrow a direction), and the guides 5 and 5 extend toward the insertion direction (arrow a direction). It has a shape inclined toward the axis n side.
[0022]
When the pin 1 is inserted into each pin insertion hole and notch provided in the resin clip 10, the guides 5 and 5 provided on the insertion direction side (arrow a direction side) of the pin 1 are the first bumper holding walls 10c. Only the notches 16 and 16 formed in can be inserted. That is, by inserting the tip of the pin 1 into a notch provided in the resin clip 10, the directionality of the pin 1 is determined, and the pin 1 can be inserted toward the insertion direction while the directionality is maintained. it can. Locking protrusions 2 and 2 projecting in a direction substantially perpendicular to the extending direction of the guides 5 and 5 are formed on the side surface 10e1 in the direction of arrow a of the fender liner holding wall 10e constituting the resin clip 10. The seat 19 is surely seated. Therefore, the mounting operation of the pin 1 to the resin clip 10 can be performed efficiently and reliably.
[0023]
