Abstract:
An engine mount comprising:a cylindrical body side metal fitting adapted to be secured to a vehicle body; an engine side metal fitting adapted to be secured to an engine; a vibration isolating base body made of an elastic rubber body interposed between said cylindrical body side metal fitting and said engine side metal fitting; and a stopper portion protruding radially outwardly from said engine side metal fitting, said stopper portion being substantially disc-shaped and disposed substantially concentrically with and spaced from the body side metal fitting, said stopper portion being arranged in such a manner that a center of curvature of an outer periphery of said stopper portion, located at one direction of two radial directions that are orthogonal to each other in a radial plane, is displaced from a center of curvature of an inner periphery of said cylindrical body side metal fitting along the one direction, wherein said stopper portion comprises an outer peripheral flange protruding radially outwardly from said engine side metal fitting, and a rubber coating that covers an outer periphery of said outer peripheral flange, wherein the outer periphery of said stopper portion, at the one direction, has a radius of curvature that is larger than a radius of curvature of an imaginary circle that passes through a single point on the outer periphery of said stopper portion and is concentric with the inner periphery of said cylindrical body side metal fitting, and wherein the radius of curvature of said stopper portion, at the one direction, is equal to or smaller than a radius of curvature of the inner periphery of said cylindrical body side metal fitting, so that contacting portions of said stopper portion, which are adapted to contact said cylindrical body side metal fitting in the one direction of the two radial directions, can contact the inner periphery of said cylindrical body side metal fitting over a wide area.
