PURPOSE: To provide a vibration insulation bush to prevent the occurrence of interference between an outer cylinder metal fitting and a main shaft fitment and ensure durability of a rubber resilient substance. CONSTITUTION: A vibration insulation bush comprises a main shaft metal fitting 1; a cylindrical rubber resilient substance 2 adhered on the outer peripheral surface of the main shaft metal fitting 1; and an outer cylinder fitment 3 pressed in the outer periphery of the rubber resilient substance 2 to compress the rubber resilient substance 2 and provided at two ends with bent parts 31 radially internally bent. The main shaft metal fitting 1 is protruded from the central part in an axial direction of the outer peripheral surface. A stopper part 12 is provided to regulated so that the bent part 31 is prevented from making contact with the main shaft metal fitting 1 when the outer cylinder metal fitting 3 and the main shaft metal fitting 1 are relatively displaced in a direction crossing a shaft at right angles. The rubber resilient substance 2 has a recessed groove 23 formed along the side wall surface of the stopper part 12. |
