[0002]

2. Description of the Related Art Conventionally, various structures have been devised as a method of attaching synthetic resin molded products to each other without using screws or adhesives. For example, the actual exploitation 63-
Japanese Laid-Open Patent Publication No. 62615 describes a resin clip holding structure having a structure in which a resin clip having an elastic engaging portion and a flanged shaft portion is held by a clip mounting seat projecting in a protruding shape on a resin member. There is. In Japanese Utility Model Publication No. 4-19225, a resin clip having an elastic engaging portion at the tip of a shaft portion and a spherical collar portion at the base end of the shaft portion is held at the collar portion. On the other hand, a resin member in which the mounting seat of the resin clip is composed of a base plate portion provided with a ridge rib and a raised support plate portion having a holding hole into which the shaft portion of the resin clip is inserted and held. The structure of the clip mounting seat of is described.

As described above, in the locking structure of the clip and the attachment part of the clip, the pedestal (jaw) is provided below the shaft of the clip, and the attachment part is provided with a keyhole-shaped holding hole. In many cases, a structure is used in which the clip is pressed in from the side where the holding hole is opened and is locked.

For example, the above-mentioned Japanese Utility Model Publication No. 4-19225 is taken up as a typical example thereof, and will be described in detail below with reference to the drawings. 6 is a perspective view showing a clip and a mounting part (mounting seat), and FIG. 7 is a sectional view showing a state where the clip of FIG. 6 is mounted on a plate member to be mounted. In FIG.
100 is a resin clip, and this clip 100
Is composed of a clip portion 100a and a circular jaw 100b having a spherical lower surface. Reference numeral 200 denotes a clip mounting part (mounting seat), and the fitting part 200 of the clip 100 is provided above the clip mounting part (mounting seat) 200.
a is provided, a keyhole-shaped holding hole 200b is bored in the upper surface, the fitting side of the holding hole 200b of the clip 100 is opened to form a fitting passage, and the inner side thereof is the fixing position of the circular clip 100. Has become. Also, the ridge 200
c is provided to clamp the jaw 100b of the clip 100 between the clip 100 and the fitting portion 200a.

FIG. 7 shows a state in which the plate member 300 to be mounted is mounted on the clip mounting component (mounting seat) 200 by the clip 100, and the circumference between the central axis of the clip 100 and the holding hole 200b is shown. Space 40 in the direction
0 is provided, and a space 500 is provided in the circumferential direction between the jaw 100b of the clip 100 and the side surface of the fitting portion 200a to facilitate press fitting.

[0006]

However, in the conventional structure of the clip and the mounting part (mounting seat) as described above, there is a dimensional play in the circumferential direction between the clip column 100c and the holding hole 200b. Therefore, there is a problem that there is play between the plate material to be mounted and the mounting accuracy is poor. Furthermore, when attaching and detaching the clip 100, the clip support 1
00c and a holding hole 200b for the mounting part (mounting seat) 200
There is a problem that the insertion opening 200d of the clip 100 is damaged, the strength varies during reuse, and the clip must be replaced.

Further, the same problem as described above is caused by the former case of Shokai 6
It can also be commonly mentioned in the holding structure of the resin clip described in Japanese Patent Laid-Open No. 3-62615.

The present invention has been made by paying attention to the problem that the mounting structure of a resin product or the like by the conventional clip system is loose and the mounting accuracy is poor, and its purpose is to: The above problems can be solved, and molded products can be mounted with one-touch without using separate parts such as clips. The mounting accuracy is high, there is no play, and the mounting structure of synthetic resin molded products can withstand reuse. Is provided.
