Claims

[Scope of utility model registration request]

An outer cylinder that is fixed to the suspension member, an inner cylinder that is placed concentrically within this outer cylinder and receives the main load in the upper and lower axial directions by inserting the vehicle body mounting shaft, etc., and a split cylinder that is divided into two vertically. An intermediate cylinder is press-fitted into the outer cylinder during assembly, and in order to connect the inner cylinder and the intermediate cylinder, the inner cylinder and its surroundings are expanded so that they are slightly separated from each other in the left-right direction. The inner cylinder is provided so as to extend horizontally across both divided pieces of the intermediate cylinder arranged therein, and to surround the inner cylinder.
a first cushion rubber to which precompression is applied based on the press-fitting of the intermediate cylinder, and a first cushion rubber that extends in the front-rear direction between the opposite side edges that are close to each other in order to connect the separated two divided pieces to each other. a second cushion rubber provided facing each other, a rubber film formed by connecting each of the opposed upper end portions of the two cushion rubbers, and a pressure applied to the outer circumferential portion of the inner cylinder at a position above the first cushion rubber. a first seal ring to be fitted; a partitioning ring press-fitted into the intermediate portion of the outer cylinder in contact with the upper part of the intermediate cylinder; and a partitioning ring extending between the partitioning ring and the first sealing ring to connect them to each other. a first diaphragm; a second seal ring that is press-fitted to the outer circumference of the inner cylinder at a position above the first seal ring; and a second seal ring that extends between and connects the second seal ring and the upper end of the outer cylinder. a second diaphragm that urges the first
A first liquid chamber consisting of a sealed space with the cushion rubber, a rubber membrane, and a second cushion rubber as a lower wall and a first diaphragm as an upper wall, and a second liquid chamber consisting of a sealed space with the first diaphragm as a lower wall and a second diaphragm as an upper wall. A liquid-filled vibration-proof mount, characterized in that a liquid chamber is formed, both liquid chambers are communicated with each other by an orifice provided in the partition ring, and a liquid is sealed in both the liquid chambers.
