(Embodiment 1)
In FIGS. 1 to 5, reference numeral 1 denotes a resin mount such as a pillar trim, a side trim, a side sill protector or the like of a car, and a mount 5 is integrally formed on the mount 1. The mounting structure according to the first embodiment of the present invention is applied and the insertion member 7 is mounted.

  The insertion member 7 is a washer-integrated bolt having a screw-like main body 9. As shown in FIG. 5, the main body 9 is inserted into a mounting hole 4 formed in a metal mounting body 3 such as an inner panel of an automobile or a side sill, and a nut (not shown) is screwed on the tip end side. Is fixed to the mount 3 described above. On the base end side of the main body portion 9, a circular first plate portion 11 as a washer is formed in a protruding manner. A sheet-like seal member 12 is integrally attached to the entire surface of the first plate portion 11 on the side of the main body portion 9 and is in close contact with the mounted body 3.

  A columnar neck portion 13 is integrally formed on the side opposite to the main body portion 9 substantially at the center of the first plate portion 11, and on the side opposite to the first plate portion 11 of the neck portion 13 a second plate portion having a rectangular plate shape A portion 15 is integrally formed substantially integrally with the first plate portion 11. As a result, the second plate portion 15 is integrally formed on the first plate portion 11 via the neck portion 13.

  The mounting seat 5 is provided with a rectangular ring shaped leg portion 17 which is integrally projected to the mounting body 1 so that a space portion S1 is formed inside. The leg portion 17 has a pair of plate-like side wall portions 17a facing each other in a substantially isosceles trapezoidal shape whose width on the front end side is narrower than that on the base end side, and one end edge of these side wall portions 17a is excluding the front end portion. A plate-like open side connecting wall 17b is connected to the entire projecting direction, and a plate-like non-opening side connecting wall 17c is to connect the other end of the side wall 17a to the entire projecting direction. It is done. At the tip end edge of each side wall portion 17a, a first recess 17d substantially U-shaped in plan view is formed which is recessed toward the base end in the region excluding both end portions.

  A seat portion 19 having a substantially rectangular plate shape is integrally formed at the end of the leg 17 so as to cover the space S1 from the end of the leg 17. The space portion S1 is open in the direction in which the leg portion 17 protrudes. At a central portion of the seat portion 19 in the direction opposite to the side wall 17a, an insertion hole 21 having a U-shape in plan view, which is open to one side on the open side connecting wall 17b, is penetrated in the plate thickness direction. Hereinafter, the direction in which the open side connecting wall 17b and the opposite side connecting wall 17c are opposite to each other is the insertion / removal direction X, the direction along the plate surface of the seat portion 19, and the direction perpendicular to the insertion / removal direction X (side wall 17a The opposite direction is referred to as the width direction Y. Further, the open side of the insertion hole 21 is referred to as the open side, and the opposite side of the insertion hole 21 is referred to as the opposite side. The neck 13 of the insertion member 7 is inserted in the vicinity of the non-opening side end of the insertion hole 21. Further, the periphery of the insertion hole 21 of the seat portion 19 is nipped by the first plate portion 11 and the second plate portion 15 of the insertion member 7.

  Inclined surfaces 23 are formed on both open ends of the seat portion 19 so that the plate thickness gradually decreases toward the open side. Further, at a portion of the inner peripheral surface of the insertion hole 21 corresponding to the inclined surface 23, the pair of guide surfaces 24 opposed in the width direction Y are inclined so as to be gradually separated from each other toward the open side of the insertion hole 21 It is formed.

  Both end edges (end edges on both sides in the width direction Y) of the seat portion 19 extending along the insertion / removal direction X are recessed inward in a region excluding the both end portions in the insertion / removal direction X The second recess 25 is formed to form a through hole 27 continuous with the first recess 17 d of the side wall portion 17 a. Further, an insertion hole 28 is formed between the open side end of the seat portion 19 and the tip of the open side connection wall 17 b of the leg 17.

  A pair of elongated flexible holding pieces 29 extending in the insertion / removal direction X are integrally formed on the surface on the non-space portion S1 side of the seat portion 19 so as to face each other in the width direction Y The holding piece portions 29 are provided so as to protrude, and bridge the seating surface portions 19 on both sides in the insertion / removal direction X of the second recess 25 (the through hole 27). The protruding height of the holding pieces 29 is set equal to or less than the thickness of the first plate 11 of the insertion member 7, and the holding pieces 29 sandwich the first plate 11 in the width direction Y. Each holding piece 29 extends in the insertion / removal direction X on both sides of the inner curved portion 29a curved so as to be recessed outward in the width direction Y and the insertion / removal direction X of the inner curved portion 29a. It is comprised with the outer side curved part 29b which curves outward. The boundary between the inner curved portion 29a and the outer curved portion 29b on the open side in the opposing surface (surface in the width direction Y) of the two holding pieces 29 is the outer peripheral edge of the first plate portion 11 in the width direction Y By pressing (contacting) from the diagonally open side, the movement of the insertion member 7 to the open side (disengagement direction) is regulated to constitute the detachment restricting portion 29c. On the other hand, the boundary between the inner curved portion 29a and the outer curved portion 29b on the opposite side of the opposite surface (surface on the inner side in the width direction Y) of both holding pieces 29 has the width direction Y along the outer peripheral edge of the first plate portion 11. By pressing (contacting) the outer diagonally opposite side from the open side, the movement of the insertion member 7 to the opposite side (insertion direction) is restricted to constitute an insertion restricting portion 29c '. As described above, the movement of the insertion member 7 in the insertion / removal direction X is restricted in a state in which the mounting body 1 is mounted on the mounting body 3, so that the mounting state is stabilized. Further, the opposing surfaces (surfaces on the inner side in the width direction Y) of the open side outer curved portions 29b constitute guide portions 29d which are gradually separated from each other toward the open side.

  Further, on both sides in the width direction Y of the insertion hole 21 of the seat portion 19, a pair of opposing wall portions 31 extending parallel to each other along the insertion / removal direction X at the central portion in the insertion / removal direction X is integrated with the space portion S1 side. It is protrusively installed. The opposing wall portions 31 restrict rotation of the insertion member 7 by sandwiching the second plate portion 15 of the insertion member 7 from both sides in the width direction Y. Further, in the seat portion 19, a pair of guide wall portions 33 which are continuous with the open side of the opposite wall portion 31 and curved so as to gradually separate from each other toward the open side are integrally formed on the space portion S1 side. It is protrusively installed.

  In order to attach the insertion member 7 configured as described above to the mounting seat 5, the second plate portion 15 of the insertion member 7 is inserted into the insertion hole 28 of the mounting seat 5 from the open side, Slide it to the open side. As a result, the first plate portion is pressed by bending the holding piece portion 29 to the outer side in the width direction Y (the outer periphery of the first plate portion 11) while the outer peripheral edge of the first plate portion 11 slides on the guide portion 29d. 11. Movement to the anti-open side is permitted. At this time, since the distance between the two guide portions 29 d gradually widens toward the open side, the first plate portion 11 can be easily inserted between the two guide portions 29 d, that is, between the two holding piece portions 29. Further, since the holding piece 29 is provided on the side opposite to the space S1 (the base end of the leg 17) of the seat portion 19 and is easy to visually recognize, the work of inserting and removing the insertion member 7 into the mounting seat 5 is easy.

  Furthermore, in this process, the second plate portion 15 is guided by the guide wall portion 33 so that both widthwise Y side edges of the second plate portion 15 provided in a rectangular shape face the both facing wall portions 31 in parallel. The entire insertion member 7 is rotated, and the second plate portion 15 reaches a position where it is sandwiched by both opposing wall portions 31 from both sides in the width direction Y. At this time, since the guide wall portions 33 are gradually separated from each other toward the open side, the second plate portion 15 can be easily inserted between the two guide wall portions 33.

  Moreover, since the guide part 29d is formed in the open side edge part of the opposing surface of each holding piece part 29, and the space | interval of both the guide parts 29d is gradually enlarged toward the open side, both the 1st board parts 11 Insertion between the holding pieces 29 is easy. Then, when the central portion of the first plate portion 11 in the insertion / removal direction X crosses over the separation restricting portion 29c of the holding piece 29, the first plate portion 11 gradually reduces the bending of the holding piece 29, while the separation restricting portion 29c and the insertion restricting portion 29c 'are guided to a position surrounded from four sides. In this state, the holding piece 29 is slightly bent outward in the width direction Y from the original shape.

  Further, the neck portion 13 is inserted into the insertion hole 21 from the open side and guided near the opposite end of the insertion hole 21, and the first plate portion 11 and the second plate portion 15 surround around the insertion hole 21 of the seat portion 19. Will be held. At this time, since the distance between the guide surfaces 24 of the insertion hole 21 gradually increases toward the opening side of the insertion hole 21, insertion of the neck portion 13 into the insertion hole 21 is easy. Furthermore, since the plate thickness of the seat portion 19 gradually decreases toward the open side at the open end of the insertion hole 21, the seat portion 19 is formed between the first plate portion 11 and the second plate portion 15. Is easy to insert.

  Next, as described above, the main body portion 9 of the insertion member 7 attached to the attachment body 1 is inserted into the attachment hole 4 of the attached body 3 and a not-shown nut is screwed to the distal end side of the main body portion 9 Attach the mounting body 1 to the mounting body 3. At this time, the insertion member 7 is positioned in the insertion / removal direction X by the separation restricting portion 29c and the insertion restriction portion 29c ′ of the holding piece 29, and the position of the insertion member 7 does not have to be adjusted in the insertion / removal direction X. Installation is easy.

  Moreover, when removing the attachment body 1 attached as mentioned above from the to-be-attached body 3, the attachment body 1 is pushed on the opposite side (Z direction in FIG. 4). Even if this pressing force acts on the mounting body 1, the insertion member 7 does not move in a state of being inserted into the mounting hole 4 of the mounting body 3, and the mounting seat 5 of the mounting body 1 moves in the opposite direction. That is, the insertion member 7 moves relative to the mounting seat 5 in the opening direction. At this time, the outer peripheral edge of the first plate portion 11 of the insertion member 7 presses the separation restricting portion 29c to the outer side in the width direction Y (the outer peripheral side of the first plate portion 11) to bend the holding piece 29 outward in the width direction Y Thus, the movement of the first plate portion 11 to the open side is permitted. Then, the central portion of the first plate portion 11 in the insertion / removal direction X gets over the detachment restricting portion 29c of the holding piece 29, slides on the guide portion 29d, and gradually reduces the bending of the holding piece 29 It leaves from 29 on the open side. Thereby, the holding piece portion 29 is released from the pressing force of the first plate portion 11 and returns to the original shape.

  Therefore, according to the first embodiment, even when the first plate portion 11 passes between the holding piece portions 29 in the process of inserting and removing the insertion member 7, the holding piece portion 29 is bent to the outer peripheral side and is not easily scraped off. Therefore, even if the insertion member 7 is repeatedly inserted and removed, the drop prevention function is unlikely to be deteriorated.

  Further, since the holding piece portion 29 functions to prevent the insertion member 7 from falling off and it is not necessary to form a bendable stopper portion on the seat portion 19 as in Patent Document 2, the strength of the seat portion 19 is enhanced. Thus, it is possible to prevent the wobbling of the insertion member 7 and the decrease in the mounting strength of the mounting body 1 to the mounted body 3.

  Further, since the holding piece portion 29 is formed to bridge the seating surface portions 19 on both sides in the insertion / removal direction X of the through hole 27, the undercut is achieved by utilizing the through hole 27 when molding the mounting body 1 Since the holding piece portion 29 can be formed without providing a portion, the holding piece portion 29 can be formed on the mounting seat 5 without using a slide mold for avoiding undercuts, and the mold structure of the mold is simplified.

In the second embodiment, the insertion member 7 is a resin clip, and the main body portion 9 is integrally continuous with the shaft portion 9 a and the tip of the shaft portion 9 a at the center, and both ends are close to the first plate portion 11 The flexible plate portion 9b is formed into a substantially V-shaped cross section, and is inserted into and locked in the mounting hole 4 of the mounted body 3 described above. In addition, the seal member 12 is not attached to the first plate portion 11, and a tapered plate shape that protrudes to the main body portion 9 side and contacts the mounted object 3 at the outer peripheral end of the first plate portion 11. The contact piece portion 11a is integrally formed over the entire circumference. The peripheral edge portion of the mounting hole 4 of the mounted body 3 is held between the flexible plate portion 9b and the contact piece portion 11a. Further, the diameter of the neck portion 13 is set shorter than the length in the width direction Y of the insertion hole 21, and a gap S2 is formed between the neck portion 13 and the inner peripheral surface of the insertion hole 21 on both sides in the width direction Y. Furthermore, the second plate portion 15 is formed in a circular shape.

  Further, the holding piece portion 29 is provided so as to protrude from the surface of the seat portion 19 on the space portion S1 side, and is constituted only by the outer side curved portion 29b on the open side. Further, the opposite open side end edge of the opposing surface of both the holding piece portions 29 is in pressure contact with the outer peripheral end face of the second plate portion 15 (the outer peripheral edge of the second plate portion 15) from the diagonally open side in the width direction Y Thus, the movement of the insertion member 7 in the detachment direction is restricted to constitute the detachment restriction portion 29c. Further, the facing wall portion 31 and the guide wall portion 33 are not formed in the seat portion 19.

  The other configuration is the same as that of the first embodiment, so the same reference numerals are given to the same components and the detailed description thereof will be omitted.

  Therefore, according to the second embodiment, since the holding piece 29 does not have to be provided on the non-space portion S1 side of the seat portion 19, the freedom of shape setting of the first plate portion 11 of the insertion member 7 is improved.

  Further, the diameter of the neck portion 13 is set shorter than the width in the width direction Y of the insertion hole 21 and the neck portion 13 can be moved in the width direction Y within the insertion hole 21. Even if an error in the width direction Y occurs at the position 4, the main body portion 9 of the insertion member 7 can be easily inserted into the mounting hole 4 of the mounted body 3.

  Further, since both holding piece portions 29 do not contact the second plate portion 15 from the opposite side and movement of the insertion member 7 in the insertion direction is not restricted, the mounting hole 4 of the insertion hole 21 and the mounting body 3 Even if an error occurs in the insertion / removal direction X at the position of (i), the main body portion 9 of the insertion member 7 can be easily inserted into the attachment hole 4 of the mounted body 3.

  In the first and second embodiments, one pair of holding pieces 29 is provided, but only one of the two holding pieces 29 may be provided.

  In the first embodiment, the holding piece 29 is in pressure contact with the outer peripheral edge of the first plate 11 in a mounted state with the holding piece 29 slightly bent outward in the width direction Y from the original shape. The original shape may be completely restored, and the detachment restricting portion 29 c and the insertion restricting portion 29 c ′ may be in contact with or spaced from the outer peripheral edge of the first plate portion 11.

  Similarly, in Embodiment 2 as well, the holding piece portion 29 is in pressure contact with the outer peripheral edge of the second plate portion 15 in a state where the holding piece portion 29 is slightly bent outward in the width direction Y than the original shape. May completely return to the original shape, and the separation restricting portion 29 c may abut or face the outer peripheral edge of the second plate portion 15 with a gap.
