In FIGS. 10 and 11, reference numeral 1 denotes a bumper rubber, and a fixing member 2 made of hard rubber having a locking portion 2a attached to the periphery of the opening of the vehicle body panel 8. And a cylindrical outer cylinder member 3 made of soft rubber provided around the fixing member 2. The upper surface of the fixed member 2 is set lower than the upper surface of the outer tubular member 3. Therefore, the trunk lid 9
When is closed, the outer cylinder member 3 first strikes as shown in FIG. 11 (a), and the outer cylinder member 3 bends outward as shown in FIGS. 11 (b) and 11 (c), as shown in FIG. As described above, only the amount of deflection increases (load P 1 → P 2 , deflection a → b), and when the trunk lid 9 is closed, the reaction force of the fixing member 2 is also added, resulting in a large reaction force characteristic (actual exploitation 64). -53650).

時のバタツキを抑えることが要望されてきている。On the other hand, a two-stage bumper rubber of this type, that is, a bumper rubber composed of an outer cylinder member and a fixing member, is used for a back door or a trunk lid, but a large speaker is attached to the weight. When applied to a trunk lid that has a back door or an air spoiler that tends to increase in weight and tends to increase in weight, the initial reaction force characteristics are increased to counteract the increase in weight, and at the time of closing. There is a demand for stabilizing reaction force characteristics and suppressing flapping during traveling.
