PURPOSE:To provide the above liquid enclosed cylindrical mount which is capable of setting the spring ratio in the right angle direction of the shafts perpendicularly crossing to each other to be larger. CONSTITUTION:In the liquid enclosed cylindrical mount where a pair of liquid chambers 46, 46 which are mutually communicated through an orifice passage 36 are provided at the position opposite to one direction of the vibration input across an internal cylindrical metal piece between the internal cylindrical metal piece 10 and the external cylindrical metal piece 12 which are communicated to each other by a rubber elastic body 14, a pair of void spaces 38, 38 which penetrate the rubber elastic body 14 and extend in the axial direction respectively are provided in the opposite position across the internal cylindrical metal piece 10 in the second vibration input direction which is orthogonal to the first vibration input direction. This arrangement allows the wall part on both sides of the circumferential direction in the liquid chamber 46 to be the vertical wall parts 40, 40 which practically extent in the first vibration input direction, and at the same time, allows the vertical wall part on both sides in the circumferential direction of the fluid chamber 46 to be thinner than that on both sides in the axial direction in the fluid chamber 46. |
