Claims

[Scope of utility model registration request]

(1) A mounting member that is connected to the engine and a base member that mounts the engine are connected by an elastic member that can be elastically deformed by transmitting vibrations to form a chamber therein, and a fluid is sealed in the chamber; In a fluid-filled engine mount in which a diaphragm is attached to a base member and a fluid chamber and a diaphragm chamber are communicated through an orifice, a plurality of recesses are formed radially in an inner wall of the elastic member facing the fluid chamber,
The recesses are formed so that the total area of the recesses is more than half the surface area of the inner wall, and the outer wall of the elastic member forming the bottom of each recess is provided with a thin film portion that bulges outward and is likely to buckle. An engine mount for injecting fluid, characterized by a plurality of radially formed. (2) The fluid container according to claim 1 of the utility model registration, characterized in that the concave portion is formed so that a continuous portion between the peripheral wall of the concave portion and the thin film portion forming the bottom thereof has an arc shape in longitudinal section. Engine mount.
