れるバンパーラバーの取付構造に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mounting structure for a bumper rubber that is attached to a vehicle body or an opening/closing body for the purpose of cushioning the opening/closing body, such as a door hood of an automobile.
従来の技術
この種のバンパーラバーの取付構造としては大別して圧
入タイプとねじ込みタイプの二つのタイプが知られてお
り、圧入タイプの代表的な構造を第２図（Ａ）、（Ｂ）
に示す（例えば特開昭５６４７３１８号公報）。BACKGROUND OF THE INVENTION There are two known types of mounting structures for this type of bumper rubber: a press-fit type and a screw-in type.The typical structure of the press-fit type is shown in Figures 2 (A) and (B).
(For example, Japanese Patent Laid-Open No. 5647318).

して抜け止め固定されることになる。In this structure, as shown in the figure (Δ), a wedge-shaped leg portion 13 is formed integrally with the main body portion 12 of the bumper rubber 11, and a rod-shaped installation tool 14 is inserted into the tool insertion hole 15. By pushing the leg 13 into the mounting hole 17 of the mating panel 16, the groove 18 formed at the base of the leg 13 fits into the periphery of the mounting hole 17, as shown in FIG. It will be fixed in place.

おのずと限界がある。その結果、バンパーラバー１１の
抜け止め効果の向上が望めない。Problems to be Solved by the Invention According to the conventional structure, the leg portion 13 must be inserted into the mounting hole 17 while being elastically deformed, which makes it difficult to achieve both ease of insertion and difficulty in removing it. In order to increase the stopping effect, it is most effective to increase the maximum diameter of the leg 13, but the larger the maximum diameter of the leg 13, the more difficult it is to insert the leg 13 into the hole 17. Therefore, there is naturally a limit to increasing the maximum diameter of the leg portion 13. As a result, it is difficult to expect an improvement in the effect of preventing the bumper rubber 11 from coming off.
本発明は以」二のような問題点に鑑みてなされたもので
、その目的とするところは、取付穴に対する脚部の挿入
の容易さを確保しつつ、抜け止め効果の向トを可能とし
たバンパーラバーの取付構造を提供することにある。The present invention was made in view of the following two problems, and its purpose is to improve the retaining effect while ensuring ease of inserting the leg into the mounting hole. The purpose of the present invention is to provide a mounting structure for a bumper rubber.
課題を解決するための手段
本発明は、円筒状のバンパーラバー本体部の内部に変形
容易部を介して略球状のアンカー部を予め一体に形成し
、円筒状の脚部を相手側の取付穴に挿入した上でアンカ
ー部を脚部側に押し込むことにより、脚部を径方向に拡
開させて抜け止め固定した構造としている。Means for Solving the Problems In the present invention, a substantially spherical anchor portion is integrally formed in advance inside a cylindrical bumper rubber main body portion via an easily deformable portion, and the cylindrical leg portion is inserted into a mating mounting hole. By inserting the anchor part into the leg part and pushing the anchor part into the leg part, the leg part is expanded in the radial direction and fixed to prevent it from coming off.
作用
この構造によると、脚部を拡開させることによって脚部

果が得られる。Function: According to this structure, by expanding the legs, the legs are caught on the peripheral edge of the mounting hole, and a sufficient effect of preventing the legs from coming off can be obtained.

1 is a bumper rubber, 2 is a mating panel to which the bumper rubber 1 is attached, and 3 is a mounting hole. The bumper rubber 1 has a hollow cylindrical main body 4 as shown in FIG.
A hollow cylindrical leg part 5 with a smaller diameter than this is integrally formed on the lower surface of the body part 4, and a substantially spherical anchor part 7 is preliminarily attached to the inner bottom part of the main body part 4 via a thin-walled easily deformable part 6. It is formed in one piece. The tip of the leg 5 excluding the base is formed into a substantially spherical shape with a predetermined curvature, and the maximum diameter of the leg 5 before being inserted into the mounting hole 3 is as large as the diameter of the mounting hole 3. It is set to

As shown in the figure, after inserting the leg portion 5 into the mounting hole 3 and seating the main body portion 4 on the panel 2, use the rod-shaped installation tool 8 to reverse the position of the anchor portion 7. Push the anchor part 7 into the leg part 5 side. When the anchor part 5 goes over the mounting hole 3 and is pushed to the bottom of the panel 2,
As shown in FIG. 2A, the leg portions 5 are expanded greatly in the radial direction, and the expanded leg portions 5 are caught on the peripheral edge of the mounting hole 3, whereby the bumper rubber 1 is fixed to prevent it from coming off.
