  However, as in the above-mentioned Patent Document 1, when the notch is formed corresponding to the tip of the leg, the clip can be easily attached to the clip attachment seat, but the attached body on which the clip has been attached is attached. If an external force such as vibration acts on the mounted body in the process of carrying it into the production line to be mounted on the mounting body, the clip may pass through the notch and fall off the seat surface.

  This invention is made | formed in view of this point, The place made into the objective is to prevent the drop-off | omission from the seat surface part of a clip, making attachment to the clip attachment seat of a clip easy.

  In order to achieve the above object, the present invention is characterized in that the structure on the leg tip side corresponding to the notch is devised.

  Specifically, the present invention has a space portion between a leg part integrally projecting on a resin-made attached body and a leg part projecting surface of the attached body, and the leg tip A seating surface portion integrally formed with the seating surface portion, and the seating surface portion includes a locking hole for locking a clip made of resin having a clip body inserted and locked into the mounting hole of the mounting body, and the clip body. An insertion hole for inserting a substantially plate-shaped insertion base formed integrally with the neck portion through the neck portion is continuously opened through the communication hole, and the opening region of the insertion hole is opposed to the communication hole. A clip body and an insertion base are formed by forming a notch extending to the tip of the clip, and guiding the neck to the locking hole while inserting the insertion base into the insertion hole from the notch and slidingly contacting the back surface of the seating surface. The clip mounting seat that attaches the above clip to the seating surface by holding the periphery of the locking hole in the seating surface And, it took the resolution means such as the following.

  That is, in the present invention, in the vicinity of the leg tip corresponding to the notch, a flexible stopper piece is integrally projected so that the tip is inclined upward toward the insertion hole. In the process of guiding the neck portion of the clip to the locking hole, the portion is pushed down to the leg base end side by sliding contact with the back surface of the insertion base portion to allow the insertion base portion to move, and the neck portion becomes the locking hole. When guided, it is restored by sliding contact with the back surface of the insertion base and faces the outer periphery of the insertion base, and is configured to prevent the clip from coming out of the locking hole. .

  According to the present invention, when the neck is guided to the locking hole as described above, the distal end of the stopper piece rises to the distal end side of the leg by releasing the sliding contact with the back surface of the insertion base and faces the outer periphery of the insertion base. Even if the clip tries to move to the notch portion side by the action of external force, the movement is restricted by the stopper piece portion and does not fall off from the seat surface portion.

  In addition, the clip can be inserted into the insertion hole and then the neck can be inserted into the locking hole by placing the insertion base of the clip on the leg end corresponding to the notch and sliding the stopper piece down. Easy installation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  In FIG. 2 (c), 19 is a resin mounting body such as a pillar trim or a side trim of an automobile, and the clip mounting seat 3 according to the embodiment of the present invention is integrally projected on the mounting body 19, A resin clip 1 is attached to the clip mounting seat 3.

  The clip 1 includes a clip body 9 that is inserted and locked into a mounting hole 7 of an attachment body 5 (shown in FIG. 2C) such as an inner panel of an automobile. A taper-plate-shaped contact piece 17 that protrudes toward the attachment body 5 and abuts against the attachment body 5 is further perpendicular to the axial direction of the clip body 9 on the further proximal side of the contact piece 17. A plate-like projecting portion 15 projecting integrally is provided. Further, a columnar neck portion 11 is integrally attached to the base end side at the substantially center of the plate-like overhanging portion 15, and a substantially disk-like shape is provided on the side of the neck portion 11 opposite to the plate-like overhanging portion 15. The insertion base 13 is integrally formed so as to project substantially parallel to the plate-shaped projecting portion 15. As a result, the clip base 9 is integrally formed with the insertion base 13 via the neck 11.

  On the other hand, as shown in FIGS. 1 and 3, the clip mounting seat 3 includes a leg portion 21 having a substantially U-shaped cross section projecting integrally with the mounted body 19. The side wall part 21a which opposes mutually and the connection wall part 21b which connects the one end side of this side wall part 21a are provided, and the opposing side of this connection wall part 21b is open | released. Further, a seat surface portion 25 is integrally formed at the tip of the leg portion 21 so as to be substantially parallel to the leg portion 21 projecting surface 19a of the mounted body 19. As a result, a space portion 23 is formed between the seat surface portion 25 and the leg portion 21 projecting surface 19 a of the mounted body 19. Further, a circular locking hole 27 for locking the clip 1 is opened at the approximate center of the seat surface portion 25. Further, an insertion hole 29 for inserting the insertion base portion 13 of the clip 1 is provided on the opposite side of the leg portion 21 in the seat surface portion 25 through a communication hole 31 narrower than the diameter of the neck portion 11 of the clip 1. The locking hole 27 is opened continuously. The diameter of the locking hole 27 is set slightly larger than the diameter of the neck portion 11 of the clip 1 and smaller than the diameters of the insertion base portion 13 and the plate-like overhang portion 15. Further, the dimension of the insertion hole 29 in the direction orthogonal to the insertion direction of the insertion base portion 13 of the clip 1 (direction orthogonal to the side wall portion 21a) is larger than the diameter of the insertion base portion 13 and is a plate-like projecting portion. The diameter is set to be smaller than 15.

The insertion hole 29 extends from the communication hole 31 to the side wall portions 21 a, and the opening area of the insertion hole 29 is the end portion of the seating surface portion 25 on the connection wall portion 21 b side, that is, the leg portion 21 that faces the communication hole 31. A notch 33 is formed so as to extend to the tip. The projecting dimension h ₁ of the leg 21 corresponding to the notch 33 from the projecting surface 19 a of the leg 21 is larger than the dimension h ₂ from the projecting surface 19 a of the leg 21 on the back surface of the seat 25. 13, a gap c is formed between the tip of the leg 21 corresponding to the notch 33 and the back surface of the seat surface 25. In the middle of the tip of the leg 21 corresponding to the notch 33 (position facing the communication hole 31), a flexible stopper piece 35 is directed toward the insertion hole 29. It is slanted upward and protrudes integrally.

In order to attach the clip 1 configured as described above to the clip mounting seat 3, first, as shown in FIGS. 2A and 2B, the insertion base 13 of the clip 1 is notched in the clip mounting seat 3. When placed on the tip of the leg portion 21 (the connecting wall portion 21b) corresponding to the portion 33, the tip of the stopper piece 35 is pushed down toward the space 23 and the tip is directed toward the locking hole 27. . When the insertion base portion 13 is slid substantially parallel to the seat surface portion 25, the surface (upper surface) is seated while the insertion base portion 13 is supported by the tip of the leg portion 21 (connection wall portion 21b) where the notch portion 33 is formed. The surface portion 25 is inserted into the insertion hole 29 in sliding contact with the back surface. Thus, the protruding dimension h ₁ of the leg 21 corresponding to the cutout portion 33 is than the dimension h ₂ from the leg portion 21 projecting surface 19a of the mounting member 19 to the seat surface portion 25 rear surface of the insert base 13 Since the thickness t is set shorter, the clip 1 can be inserted into the insertion hole 29 by placing the insertion base 13 on the tip of the leg 21 corresponding to the notch 33 of the clip mounting seat 3 without tilting the clip 1. Work can be done easily.

  When the insertion base portion 13 is further slid in the direction of the locking hole 27 substantially parallel to the seating surface portion 25, the stopper piece 35 has its tip directed toward the locking hole 27 by sliding contact with the insertion base portion 13. In the state, the insertion base portion 13 is allowed to move, and the neck portion 11 is displaced so as to widen the communication hole 31 and passes through the communication hole 31, and then into the locking hole 27 as shown in FIG. Insertion is guided. In this inserted state, the stopper piece 35 is released from the pressing force by the insertion base 13 and is elastically restored to the side opposite to the space 23 (upward), and the tip of the stopper piece 35 is located at the insertion base 13. It comes to be located above the back surface. Further, in this inserted state, the plate-like projecting portion 15 of the clip body 9 and the insertion base portion 13 sandwich the periphery of the locking hole 27 of the seat surface portion 25. Since the communication hole 31 is slightly narrower than the diameter of the neck portion 11 in the clip 1, the neck portion 11 is prevented from coming out to the insertion hole 29 side through the communication hole 31. Further, when an external force in the anti-insertion direction of the clip 1 acts on the clip 1 during transportation or the like, as described above, the stopper piece portion 35 faces the outer peripheral edge of the insertion base portion 13 with a slight gap therebetween. The insertion base 13 abuts against the stopper piece 35 and prevents the clip 1 from coming out of the seat surface 25.

  The clip 1 thus attached to the clip attachment seat 3 is attached to the attachment body 5 by inserting the clip body 9 into the attachment hole 7 of the attachment body 5 as shown in FIG.

  If the tip of the stopper piece 35 is positioned above the back surface of the insertion base 13 with the clip 1 attached to the clip mounting seat 3, the base end of the stopper piece 35 is connected to the notch 33. You may provide below the front-end | tip of the corresponding leg part 21. FIG. Further, the stopper piece 35 does not necessarily have a shape along the insertion direction as shown in FIG. 2B, and crosses the insertion direction, that is, the tip of the stopper piece 35 does not face the communication hole 31. It may be formed.

Further, if the stopper piece 35 is formed long so that the tip of the stopper piece 35 is located above the back surface of the insertion base 13 in a state where the clip 1 is attached to the clip attachment seat 3, it corresponds to the notch 33. protruding dimension h ₁ of the legs 21 may be set shorter than the above-described embodiment.

  Further, if the stopper piece 35 can prevent the clip 1 from being detached while the clip 1 is attached to the clip mounting seat 3, the stopper piece 35 is not in the middle of the tip end of the leg 21 corresponding to the notch 33 but the leg corresponding to the notch 33. You may project in the vicinity of the tip of the portion 21.
