まうという欠点があつた。 In such a plastic bumper, since the bumper body 1 and the fastener 2 are inseparable, there are advantages such as improved installation workability on the vehicle body 3, etc., and the possibility of losing the fastener 2. Due to the nature of integrally molding the bumper body 1 and the fastener 2, there is a so-called sink mark 5 on the outer surface of the bumper body 1 where the fastener 2 is formed.
There was a drawback that the sink mark 5 caused the appearance to deteriorate.

It consists of a curved plate-shaped spacer piece 2d that presses the inner circumferential surface and applies an appropriate restoring force to them to keep them at a predetermined distance. When fitting into 4, it bends due to its elasticity,
After fitting, an expanding force is applied to the parallel pieces 2b, 2c to make it difficult for these parallel pieces 2b, 2c to come off from the attachment hole 4.

It is a hole-shaped hollowed out part provided in the joint part (connecting part) of. These hollowed out parts 6...6 are provided in the spacer piece 2d as shown in FIGS.
As shown in Figures 6 to 6, they are provided on the spacer piece 2d and the parallel pieces 2b and 2c. Note that 7...7 are non-thickened parts, and the non-thickened parts 7...7 maintain the required bonding strength between the bumper body 1 and the fastener 2.

けたので次に述べるような効果がある。 As described above, the present invention provides a plastic bumper in which the bumper body and fasteners are integrally molded from plastic, and the bumper body is attached to the vehicle body etc. by fitting the fasteners into mounting holes provided in the vehicle body etc. A pair of parallel pieces having a locking protrusion on the outer circumferential surface and a pair of parallel pieces are installed between these parallel pieces, and the inner circumferential surfaces of both are pressed down and an appropriate restoring force is applied to them to hold them both at a predetermined level. The fastener is formed of curved plate-shaped spacer pieces that are kept at a certain distance from each other, and a hole-shaped hollowed part is provided at the joint between the fastener and the bumper body, so that the following effects can be obtained.

形成したので、実開昭56−143142号公報のよう

に比べて、成形時におけるヒケの発生を著しく
減少させることができる。(1) Since the fastener is formed of a pair of parallel pieces having locking protrusions on the outer circumferential surface and a spacer piece that straddles between these parallel pieces and keeps them at a predetermined distance, it is possible to Compared to the fastener formed in a cylindrical or prismatic shape as in Japanese Patent No. 56-143142, the occurrence of sink marks during molding can be significantly reduced.
(2) スペーサー片により並行片の取付孔への挿入

付孔へのフアスナーの嵌合が容易になり、かつ
嵌合後は抜け難くなる。(2) The spacer piece makes it easier to insert the parallel piece into the mounting hole. In particular, when a hole-shaped hollow part is formed at the joint of the spacer piece with the bumper body, the spring force of the spacer piece is fully exerted, making it easier to fit the fastener into the mounting hole, and the fit is improved. After that, it becomes difficult to get out.
(3) 孔状の肉抜部でヒケを防止する構成としたの
で中空状部でヒケを防止する場合に比べてフア
スナーの成形が容易になる。(3) Since the structure is such that sink marks are prevented with a hole-shaped hollowed out part, it is easier to mold the fastener compared to a case where sink marks are prevented with a hollow part.
