Abstract

PROBLEM TO BE SOLVED: To provide an inexpensive bumper rubber causing no buckling. SOLUTION: This bumper rubber 2 installed on either of an opening and closing member and a peripheral edge of an opening for installing the opening and closing member is made of rubber or thermoplastic elastomer, and a recessed part 18 is formed at a pressure receiving face 16 on the top. Plural recessed grooves 20 continuously provided over the whole peripheries, are formed on the side face of the bumper rubber. The farther the respective recessed grooves are away from the pressure receiving face 16, the deeper the grooves 20 are formed so that the outside diameter of remaining central part becomes smaller as it far from the pressure receiving face 16. Thus, a bumper rubber 2 made up of a single member can be obtained, and the cost of the bumper rubber 2 can be reduced and the bumper rubber 2 can be prevented from causing backling.

2. Description of the Related Art A bumper rubber is interposed between a periphery of an opening of a vehicle body in which a trunk lid is provided and the trunk lid in order to reduce an impact when the trunk lid is closed. As such a bumper rubber, a shaft member capable of moving up and down in parallel with the opening and closing direction of the trunk lid is housed inside, and the shaft member is urged by a coil spring (for example, Japanese Utility Model Laid-Open No. 4-11942). The impact of closing the trunk lid is reduced by the spring force of the coil spring.

If the mounting side of the bumper rubber to the trunk lid is formed of a hard resin or the like, when the trunk lid is closed, the portion of the trunk lid where the bumper rubber is mounted is deformed, so that the bumper rubber is disposed. Depending on the position, the surface distance between the trunk lid and the vehicle body opening changes, and there is a possibility that the impact when the trunk lid is closed cannot be effectively reduced by the bumper rubber.

According to a first aspect of the present invention, an opening / closing member and one of the peripheral edges of an opening to which the opening / closing member is attached are alleviated to reduce an impact when the opening / closing member is closed. The bumper rubber is made of rubber or thermoplastic elastomer, has a concave portion formed on the pressure receiving surface at the tip, and has a plurality of continuous concave grooves formed on the side surface over the entire circumference, and the remaining central portion is the above-mentioned. Each of the concave grooves is formed deeper as the distance from the pressure receiving surface decreases, so that the groove becomes thinner as the distance from the pressure receiving surface increases. As a result, a single-part bumper rubber can be obtained, and since the bumper rubber is made of rubber or a thermoplastic elastomer,
The opening / closing member to which the bumper rubber is attached or the periphery of the opening can be prevented from being deformed when the opening / closing member is closed.
