Claims

[Scope of utility model registration request]

An inner cylinder, an outer cylinder externally fitted to the inner cylinder with a space between them, and a rubber elastic body interposed between the two cylinders create upper and lower liquid chambers that sandwich the inner cylinder, and an outer cylinder. and an orifice flow path that communicates the two liquid chambers along the inner periphery of the outer cylinder, and connect the two liquid chambers together. A pair of upper and lower semi-cylindrical orifice members, each having a circumferential rib that protrudes on the center line of the outer periphery and has a through hole to both liquid chambers on one side, are used to connect the upper and lower liquid chambers. In a vibration damping mount that is inserted into a path and fitted against each other via an elastic body, the upper and lower orifice members are placed on both sides of the outer periphery and on the center line, except for one end formed in a U-turn path. forming an identical member of the same shape with a protruding rib in the direction and a through hole to both liquid chambers bored at a predetermined position on one side of the rib, and the two members are attached to the inner periphery of the outer cylinder, A cylindrical liquid-filled anti-vibration mount characterized in that one end is inverted relative to a rib and assembled vertically, and the other end is butt-fitted through at least one elastic body.
