Claims

[Claims for Utility Model Registration] (1) An inner cylindrical metal fitting and an outer cylindrical metal fitting arranged concentrically or eccentrically at a predetermined distance from each other in the radial direction, and a rubber elastic body interposed between them. and between the inner cylindrical metal fitting and the outer cylindrical metal fitting,
In a cylindrical mount device that is provided with a cavity that penetrates in the axial direction and extends approximately half the circumference in the circumferential direction, a rubber elastic body having a shape that substantially corresponds to the shape of the inner peripheral surface of the cavity is inserted into the cavity. By inserting and arranging a stopper member, and supporting the inner cylindrical metal fitting side so as to contact the inner circumferential surface of the hollow space on the inner cylindrical metal fitting side, the inner periphery of the hollow space on the outer cylindrical metal fitting side of the stopper member The amount of relative displacement in the radial direction between the inner cylindrical metal fitting and the outer cylindrical metal fitting is regulated by contact with the surface, while the contact surface between the stopper member and the inner circumferential surface of the cavity is A cylindrical mount device characterized in that at least one of the abutting surfaces between the stopper member and the inner circumferential surface of the hollow space on the outer cylindrical metal fitting side is provided with embossed irregularities. (2) The cylindrical mount device according to claim (1), wherein a lubricant is applied to a contact surface between the stopper member and the inner circumferential surface of the cavity, on which the textured unevenness is applied. . (3) the rubber elastic body is configured to be attached to the outer cylindrical fitting by vulcanizing and adhering a metal sleeve to the outer peripheral surface of the rubber elastic body and press-fitting the metal sleeve into the outer cylindrical fitting; A pocket portion that penetrates the metal sleeve and opens to the outer circumferential surface is provided in a portion between the inner cylindrical metal fitting and the outer cylindrical metal fitting that is located on the opposite side in the radial direction from the space, and an opening of the pocket portion is provided. By covering with the outer cylindrical metal fitting, a part of the wall is made of the rubber elastic body, and a predetermined incompressible fluid is sealed inside, which causes internal pressure fluctuations when vibration is input. While forming a pressure receiving chamber, the metal sleeve is recessed radially inward in a portion between the inner cylindrical metal fitting and the outer cylindrical metal fitting where the space is located, so that the inside of the recessed portion of the metal sleeve is recessed. The peripheral surface constitutes an inner circumferential surface on the outer cylindrical metal fitting side of the space against which the stopper member comes into contact, and between the recessed part of the metal sleeve and the outer cylindrical metal fitting,
An equilibrium chamber is formed, at least a portion of which is made of a flexible membrane, and a volume change is allowed, and a predetermined incompressible fluid is sealed therein, and the pressure receiving chamber and the equilibrium chamber are 2. The cylindrical mount device according to claim 1, further comprising an orifice passage that communicates with each other and allows fluid to flow between the two chambers.
