Description of the Related Art As shown in FIG. 8, a conventional anti-vibration device called a toe collect bush has a longitudinal direction of the vehicle at both longitudinal ends of a twist beam 10 arranged in the longitudinal direction of the vehicle. A pair of trailing arms 11 and 12 arranged in the direction is provided, and cylindrical bush press-fitting portions 11A and 12A are formed at the front end portions of these trailing arms 11 and 12, respectively, and these bush press-fitting portions 11A and 12A are formed. It was pressed in and used. Also,
A reinforcing member 13 is welded to a connection portion between the twist beam 10 and the trailing arms 11 and 12, and the rear ends of the trailing arms 11 and 12 are provided with spindles 14 and 15 toward the outside of the vehicle. Are projected, and the left and right tires are supported by these spindles 14 and 15. As shown in FIG. 7, the bush press-fitted into the bush press-fitting portions 11A and 12A is provided with a rubber-like elastic body 3 between an inner cylinder 1 and an outer cylinder 2, and one end side of the outer cylinder 2 (the right end in the figure). ) Is bent outward in the radial direction, a part of which extends obliquely to form an inclined bent portion 2A, and a remaining part of which forms a flat bent portion 2B which extends almost at right angles to the outer cylinder 2, and the inner cylinder 1 is inclined to an outer periphery near one end. A plate 20 composed of an inclined portion 20A and a flat portion 20B extending substantially in parallel with each other is fixed to the portion 2A and the flat bent portion 2B, and the rubber-like elastic body 3 is curled 4 from the other end side toward the flat portion 20B of the plate 20. Is formed. One end of the currant 4 extending in the axial direction is closed by a thin film portion 5. Therefore, the currant 4 is formed only up to one end side of the outer cylinder 2.

体３は薄膜部５に形成してある。As in the conventional example shown in FIG. 7, since the thin film portion 5 exists only at the bottom of the currant 4, the thin film portion 5 can be vertically or longitudinally or twisted in the drawing. When a force is applied to the thin film portion 5, the thin film portion 5 is repeatedly pulled, which may cause a crack. When the thin film part 5 cracks, it expands to other rubber-like elastic bodies 3,
The durability of the rubber-like elastic body 3 may be impaired. Also,
From the aspect of spring characteristics, the currant 4 may require a length in the axial direction exceeding one end side of the outer cylinder 2, but in the conventional example, it is shorter than the axial length of the outer cylinder 2. Although it is conceivable that one end side of the currant 4 is penetrated, it is possible to make a rounding (formed on a curved surface with a radius R) so as to eliminate the corner portion of the peripheral edge of the rubber-like elastic body 3 at the penetrated place. Although desired from the standpoint of strength, there was a case where R-attachment could not be performed due to manufacturing, so that the bottom of the currant 4 had to be provided. The rubber-like elastic body 3 forming this bottom is formed on the thin film portion 5.

An object of the present invention is to provide an anti-vibration device having improved property.

を向上させることができる。As described above, according to the present invention, the rubber-like elastic body is provided between the inner cylinder and the outer cylinder, and one end of the outer cylinder is bent outward in the radial direction so that a part thereof extends obliquely. The remaining part is formed into a flat bent part that extends substantially at right angles to the outer cylinder, and the tilted part and the flat part that extend substantially parallel to the tilted bent part and the flat bent part are formed near the one end of the inner cylinder. In a vibration-damping device in which a plate consisting of and is formed and a curls is formed on the rubber-like elastic body from the other end toward the flat part of the plate, the tip of the plate is aligned with the flat bent part of the outer cylinder.

A part of the glue that opens at the other end of the outer cylinder and extends beyond one end of the outer cylinder to the vicinity of the recess of the plate, and extends from the bottom of the glue near the recess of the plate toward the plate
Also , since the portion of the outer cylinder facing the one end side is formed from the thin film portion of the rubber-like elastic body, the currant can be made longer (deeper), and optimal spring characteristics can be realized. Also, since the thin film portion is long, even if radial expansion and contraction is applied to this vibration isolation device, the thin film portion formed of a rubber-like elastic body that faces the one end side of the outer cylinder from the bottom integrally follows the expansion and contraction. However, it can be prevented that only the thin film portion forming the bottom is pulled and a crack is generated at this portion. When the thin film portion of the bottom is pulled, the thin film portion of the portion facing the outer cylinder also extends from the bottom, and the portion of the rubber-like elastic body consisting of these thin film portions easily elastically deforms, and the elasticity of more parts The deformation can be allowed, and the durability of the rubber-like elastic body can be improved.
