Claims

[Scope of utility model registration request]

A vibration isolating rubber body is disposed between the inner cylinder and an outer cylinder disposed axially aligned with the inner cylinder, and a plurality of liquid chambers are formed within the vibration isolating rubber body, and a plurality of liquid chambers are formed on the outer periphery of the outer cylinder. In this method, a ring member having a U-shaped cross section is fitted with its bottom surfaces in contact with each other, and openings provided at different positions on the bottom surface are communicated with each of the liquid chambers through openings provided in the outer cylinder. A liquid-filled anti-vibration bushing in which the fitted outer cylinder is press-fitted into a cylindrical seal sleeve, and the open space of the ring member is closed by the inner circumferential wall of the seal sleeve to form a throttle flow path communicating between the liquid chambers. The ring member is made of a flexible material, and one place in the circumferential direction is cut out, and the ring member is expanded in diameter and fitted onto the outer periphery of the outer cylinder, and with the cut part closed, it is inserted into the seal sleeve. A liquid-filled anti-vibration bushing characterized by being press-fitted into a position.
