Claims

[Scope of utility model registration request]

By connecting the engine side bracket and the body side bracket via the mount elastic member, and extending both brackets to the side of the mount and facing the mount axis in a direction perpendicular to the mount axis, both brackets can each absorb the primary resonance vibration of the engine mount bracket. In an automobile engine mount in which a stopper is formed to restrict excessive relative displacement in a direction orthogonal to the mount axis of both brackets, one bracket has a dynamometer for reducing secondary resonance of the mount bracket, which is composed of a damper elastic member and a damper mass. What is claimed is: 1. An engine mount for an automobile, which supports a dynamic damper, and further comprises: the damper mass of the dynamic damper being disposed between the two stoppers, and a cushion elastic member being provided on the contact surface of both the brackets and the damper mass.
