PURPOSE:To secure the superior vibrationproof effect by forming a projection part made of hard material on one side of an inner or outer cylindrical metal fitting which does not support an action member, and constituting the wall part in the mount axis direction of a fluid chamber, in the fluid seal type cylindrical mount which is suitable for the suspension of an automobile. CONSTITUTION:An upper support for suspension is formed by integrally connecting an inner cylinder metal tool 10 and an outer cylinder metal tool 12 by the first and second rubber elastic bodies 14 and 15, and the first rubber elastic body 14 is constituted as an integral vulcanization shaped article 30 which integrally has the inner and outer cylindrical metal tools 10 and 12. An annular fluid chamber 33 is formed by assembling the second rubber elastic body 15 to the vulcanization shaped article 30, and the fluid chamber 38 is divided into a pair of divided chambers 42 by an acting metal titting 40. In this case, the first projection part 22 is integrally formed in the radial direction on the inner cylindrical metal tool 20, and the second projection part 36 is formed on the inside installation metal fitting 32 of the vulcanization shaped article 30, so as to have the projection height (c) larger than the dimension (a) of the gap of a narrowed fluid passage 44. |
