In FIG. 1, reference numeral 1 denotes a bumper rubber, which is composed of a hard inner member 3 having a locking portion 3A attached to the periphery of the opening of the vehicle body panel 2 and a tubular outer member 4 provided around the inner member 3. ing. The upper surface of the inner member 3 is set lower than the upper surface of the outer member 4. Therefore, when the trunk lid 5 is closed, the outer member 4 comes first and the outer member 4 bends outward as shown in FIG. 6, and only the amount of deflection increases (load P 1 → P 2 , deflection a → b) Further, when the trunk lid 5 is closed, the reaction force of the inner member 3 is also added, and a large reaction force characteristic is obtained (Actual exploitation Sho 64-53650).

反力が開閉体に作用する。When the opening / closing body is closed, the inner member and the outer member both form a large pressure receiving surface to receive the opening / closing body with a high reaction force. Then, when the bumper rubber is further pressed, the claws of the inner member press the protrusions of the outer member to bend the outer member outward, and suppress the reaction force from increasing by the outer member. When the claw of the inner member rides over the protrusion of the outer member to close the opening / closing body, a constant reaction force acts on the opening / closing body by the spring via the inner member.

なり、したがって高い反力でトランクリッドを受けるこ
とができる。According to the structure of the above embodiment, when the trunk lid 7 comes into contact with the upper surface 20A of the cushion 20 of the inner member 9 as shown in FIG. 1, the load applied to the cushion 20 is outside the inclined surface 22 of the cushion 20. Since the upper surface 20A of the cushion 20 of the inner member 9 and the upper surface 10A of the outer member 10 are substantially aligned with each other by being transmitted to the outer member 10 via the inclined surface 17 of the member 10, the pressure receiving area becomes large, and You can receive the trunk lid with a high reaction force.
【００２０】よって、エアスポイラ等が設けられ重量が
増加したトランクリッド７を高い初期反力で保持するこ
とができる。Therefore, the trunk lid 7 provided with the air spoiler and the like and having an increased weight can be held with a high initial reaction force.

外側部材１０の突起１８を乗り越えようとして外側へ押
圧するため、外側部材の周壁１６は外側へ湾曲する。Next, when the bumper rubber 6 bends to some extent, the claws 24 of the holder 21 of the inner member 9 push outward toward the projections 18 of the outer member 10 as shown in FIG. Bends outward.
【００２２】そして、上記爪２４が突起１８から外れて

続けるため反力は小さく、したがって、トランクリッド
７は主として内側部材９のスプリング１１によって一定
のバネ定数で反力を受けることとなる。Even when the claw 24 is disengaged from the protrusion 18, the peripheral wall 16 of the outer member 10 continues to bend as shown in FIG. 3, so that the reaction force is small. Therefore, the trunk lid 7 mainly springs the inner member 9. 11, the reaction force is received with a constant spring constant.
【００２３】その結果、トランクリッド７の閉時におい

で支持することができる。As a result, a constant spring constant is maintained when the trunk lid 7 is closed, and the trunk lid 7 can be supported with an optimum spring constant that does not cause fluttering during traveling.
【００２４】このようにして、初期反力を高め、外側部
材１０を確実に湾曲させることで、最終的には最適な状
態でトランクリッド７を支持するのである。In this way, the initial reaction force is increased and the outer member 10 is reliably curved, so that the trunk lid 7 is finally supported in an optimum state.

ンクリッド、バックドア等の重量増加に対して十分に対
応することができる。As described above, according to the present invention, since a large pressure receiving area can be formed by the inner member and the outer member, the initial reaction force can be increased and the weight of the trunk lid, the back door, etc. can be increased. It can fully cope with the increase.

数でトランクリッドを最適に支持することができる。Further, when the amount of deflection exceeds a certain amount, the claws of the inner member press the outer member to press the projections of the outer member to bend outward, so that the reaction force by the outer member becomes smaller thereafter, and the inner member becomes smaller. The trunk lid can be optimally supported with a constant spring constant due to the spring force of.
