を介在させたものを上下に２つ使用している。2. Description of the Related Art A conventional vibration isolator of this type is shown in FIG.
It is known that one of the suspension arms 100 supports a tire 101 and the other is attached to a bush assembly 102, and the bush assembly 102 is attached to a bracket 104 fixed to a vehicle body 103 as shown in FIG. For details of the bush assembly 102, as shown in FIG. 6, the cylindrical portion 100A of the suspension arm 100 is an outer cylinder 102.
The bush assembly 1 is attached to the inner cylinder 102B.
Mounting shaft 10 for mounting 02 on the bracket 104
5 is inserted. An elastic body 102C such as rubber is provided between the outer cylinder 102A and the inner cylinder 102B. In this conventional example, an elastic body 102C is provided between the inner and outer cylinders 102A and 102B.
The two with the intervening are used up and down.

ですぐり４を形成してある。In the first embodiment of the present invention shown in FIG. 1, an elastic body 3 is interposed between an inner cylinder 1 and an outer cylinder 2 so that the inner cylinder 1 is longer than the outer cylinder 2 and is substantially parallel to each other. As it grows
Flanges 1A and 2A extending substantially in parallel with each other from the ends of the inner and outer cylinders 1 and 2 toward the radially outer side are formed. The elastic body 3 is also interposed between the flanges 1A and 2A so that the flanges 1A and 2A can compress the elastic body 3 therebetween when the inner cylinder 1 and the outer cylinder 2 relatively move in the axial direction. Is configured. Further, a currant 4 is formed in a portion orthogonal to the axial direction at a portion where the twisting force of the elastic body 3 between the flanges 1A and 2A is input.

In this second embodiment, the curls 4 are formed on both left and right sides. This curse 4 effectively acts on the input of a twisting force that rotates in the left and right directions from the upper axis of FIG.

保できるものである。As described above, according to the present invention, since the curl is formed in the portion of the elastic body between the flanges where the prying force is input in the direction orthogonal to the axial direction, the prying direction is different from the conventional one. There is no case where local strain or stress is generated in the elastic body at the time of input and durability is not improved. Since such local strain or stress does not occur, durability is also improved. Furthermore, since the elastic body is arranged in the portion between the flanges other than the direction in which the twisting force is generated, the spring in the axial direction can be secured.
