Claims

[Claims for Utility Model Registration] 1. A rubber layer and an intermediate cylinder are interposed in the space between the inner cylinder to which spacers are attached at both ends and the outer cylinder included between the two spacers, and vulcanization bonding is applied. In the bushing having a two-layer rubber structure, the intermediate cylinder is provided shorter than the inner cylinder and is buried in the rubber layer, and the rubber layer is interposed in a compressed state in the axial direction between the two spacers. Features a two-layer rubber bushing. 2. The two-layer rubber bushing according to claim 1,
A two-layer rubber bushing characterized by having slits long in the axial direction at radially symmetrical positions in the axial center of the intermediate cylinder.
