Claims

[Claims for Utility Model Registration] (1) A rubber elastic body is provided between an inner cylinder and an outer cylinder arranged concentrically, the inner cylinder is elastically supported by the outer cylinder, and an engine is mounted on the inner cylinder. In a vehicle engine mount in which bolts are fixed and the outer cylinder is fixed to the vehicle frame, the rubber elastic body is joined at its center to the outer periphery of the inner cylinder so that the circumferential surface has a cross section U.
It is composed of a membrane body with a predetermined elastic modulus that is curved into a letter shape, and the outer circumference of the membrane body facing the center part is joined to the inner circumference of the outer cylinder, and the relative relationship between the inner cylinder and the outer cylinder due to vibration input is An engine mount for a vehicle in which the rubber elastic body is curved and deformed as the position changes to generate a spring force. (2) The inner and outer circumferential parts of the rubber elastic body are made to extend along the outer circumference and inner circumference of the outer cylinder, which face each other, so that when the inner cylinder moves in the radial direction, they come into contact with each other and stop the movement. An engine mount for a vehicle according to Claim 1 of the Utility Model Registration Claim, wherein the engine mount is a stopper portion for restraining the vehicle. (3) Scope of the second claim for utility model registration, in which the thickness of the stopper portion is made thicker than the peripheral surface of the rubber elastic body.
Engine mount for the vehicle mentioned in section. (4) Both ends of the inner cylinder are made to protrude outward from the outer cylinder, and disc-shaped stopper members made of a rubber body are provided at both ends to face the end surfaces of the outer cylinder,
A stopper wall is configured to restrict axial movement of the inner cylinder, and a stopper wall projects from the stopper member onto a stopper portion on the outer periphery of the inner cylinder, and the stopper wall and the stopper portion form a stopper of a predetermined thickness. The engine mount for a vehicle according to claim 2, which is configured to form a body.
