Claims

[Claims for Utility Model Registration] A liquid 6 seal is provided in a rubber elastic body 3 molded between an outer cylinder 1 and an inner cylinder 2 which are arranged in parallel, and which is communicated by an orifice 5 in the vibration direction between a partition wall 3a and a side wall 3b. The liquid chamber 4 of a liquid-sealed elastic bushing having separate liquid chambers 4
A stopper 10 for restricting excessive displacement of the outer cylinder 1 or the inner cylinder 2 housed inside, the stopper 10 being installed along the inner periphery of the outer cylinder 1 between the ends 3aa of the partition wall 3a. In addition, the end portion 3aa of the partition wall 3a and the end portion 3
A certain range 1a of the inner circumference of the outer cylinder 1 away from aa
A stopper for a liquid-sealed elastic bushing characterized in that a wing-shaped part 10a is formed in contact with the side wall 3a, and the remaining part is a narrow bridge part 10b that creates a gap between the side wall 3a and the side wall 3a. . A stopper for a liquid-sealed elastic bushing as set forth in claim 1, wherein a rigid core member 11 is provided within a stopper 10. A core material 11 is attached to a portion of the wing-shaped portion 10a and the bridge portion 10b that abuts over an end 3aa of the partition wall 3a and a certain range 1a of the inner circumference of the outer cylinder 1 that is separated from this end 3aa. A stopper for a liquid-sealed elastic bushing as set forth in claim 1 of the utility model registration.
