５を車体パネル２の申付穴２ａ内に嵌合固定している。Conventional technology Traditionally, bumper rubber has been devised to absorb the impact when opening and closing the hood by attaching bumper rubber to the front end of the vehicle, which constitutes the engine compartment of the vehicle, on the body panel side or the hood panel side. It is shown in Figure 3. In the figure, 1 is a hood panel, 2 is a vehicle body panel, and a hood bumper rubber 3 inserted between the two has a base 4 and a fastener 5 protruding from this mounting base 4, and the fastener 5 is connected to the vehicle body panel. It is fitted and fixed in the notification hole 2a of No. 2.

In this configuration, since the entire structure was made of a single piece of hard rubber, the magnitude of the load applied by the hood panel 1 and the degree of deflection of the hood bumper rubber 3 in response to it are shown in Figure 4. The problem was that it was determined like a graph, and there was no degree of freedom.

う欠点があった。When the hood panel 1 comes into contact with the cylindrical protrusion 6, the cylindrical protrusion 6 is compressed and exhibits a small spring constant until its length is shortened, and when further compressive force is applied. , the spring constant is set to be high. Therefore, according to the dimensions of i and φa, the fourth
The relationship between load and deflection as shown in the figure is determined, and there is no degree of freedom such as applying it to vehicle types other than the one to which it is applied.
There is a drawback in that many types of hood bumper rubbers with different He and φ dimensions must be prepared for each vehicle model.
