Claims

[Scope of utility model registration request]

In the bushing, which has a triple cylinder structure and has a two-layer rubber structure in which a rubber layer is interposed between the inner cylinder and the intermediate cylinder and between the intermediate cylinder and the outer cylinder, the intermediate cylinder has a vertical slit that extends in the axial direction and a vertical slit that extends in the axial direction. Two or more I-shaped notches each consisting of a pair of horizontal slits connected to each other at both ends of the vertical slit and extending in the circumferential direction with the same length are provided at rotationally symmetrical positions about the cylinder axis. A bushing characterized in that a rubber layer between an inner cylinder and an intermediate cylinder is compressed.
