Abstract:
1. An antivibration device designed to be provided between an engine and a vehicle body so as to mount the engine on the vehicle body while dampening vibration of the engine, comprising: a vehicle body-side fixing member which has a base portion adapted to be fixed to the vehicle body, and a pair of sidewall portions provided to protrude from the base portion in mutually opposed relation; a shaft member which extends to couple between the pair of sidewall portions of the vehicle body-side fixing member; an engine-side fixing member adapted to be fixed to the engine and provided between the pair of sidewall portions to surround around the shaft member; an elastomer stopper member integrally provided on an inner surface of the engine-side fixing member and having an annular stopper surface defining a penetrating hole for allowing the shaft member to pass therethrough, the annular stopper surface and an outer surface of the shaft member being spaced from each other at a predetermined gap over an entire axial length of the stopper member; a thin film-shaped support body provided between the annular stopper surface and the shaft member to mutually couple the stopper member and the shaft member so that the shaft member can move in a radial direction relative to the annular stopper surface; and an elastomer mount body provided to couple the base portion of the vehicle body-side fixing member and the engine-side fixing member together.
