Abstract
In an engine mount (A) whose axis (X) is oriented in the front to rear direction of a vehicle, a damper weight (12) is embedded within a toroidal stopper rubber (10) fixed at its inner periphery to the rear end of an inner cylinder (2). The damper weight (12) is made of, for example, steel plate to have a spiral form and placed to surround the inner cylinder (2), thereby itself functioning as a spring in the direction of the axis (X). This structure can ensure a necessary mass for the damper weight while saving space, and prevent the occurrence of an uncomfortable shock when a stopper works.
