Claims

[Claims for Utility Model Registration] 1. For an inner cylinder and an outer cylinder arranged concentrically, a main body rubber is provided surrounding the inner cylinder and extending in the left and right radial direction, so that the two cylinders are connected and integrated. On the other hand,
A vibration isolator in which a pair of stopper rubbers are arranged on both sides of the main body rubber in the front and rear direction with a space left therein, and are fixed to the inner wall of the outer cylinder,
The outer cylinder has one or two opposing cracks extending in the axial direction, and when press-fitted into the suspension member, is formed into a cylinder that can be deformed in the direction of diameter reduction due to aperture, while the main rubber is Due to compressive deformation due to the press-fitting of the outer cylinder, the front and rear sides of the area surrounding the inner cylinder maintain a very small space of 1.0 mm or less with respect to both stopper rubbers, or make line contact in the axial direction. Alternatively, a vibration isolator for a suspension member is formed by forming a long and narrow rubber layer that can make surface contact. 2. Claim 1: The inner cylinder has a protrusion extending in the axial direction and protruding outward at the front side in the front-rear direction.
Vibration isolator for the suspension member listed.
