FLUID SEALED TYPE VIBRATION ISOLATOR

Japanese Patent JP2018112231

A

PROBLEM TO BE SOLVED: To provide a fluid sealed type vibration isolator having a new structure being capable of simply fixing an orifice member and a cover plate member.SOLUTION: In a fluid sealed type vibration isolator 10 comprising an orifice member 40 which forms an orifice passage 84 disposed between fluid chambers 80 and 82, in which at the oscillatory input time, relative pressure fluctuations are produced, so as to communicate the fluid chamber 80 with the fluid chamber 82, a cover plate member 42 is overlapped on the orifice member 40; by press fitting a force fit pin 56 projected from the overlap mating surface of the cover plate member 42 in the orifice member 40 into a press-in hole 64 penetrated the cover plate member 42, the cover plate member 42 is fixed in a state in which the cover plate member is overlapped on the orifice member 40; at the tip of the force fit pin 56, a tip inclined face 58 is provided which becomes a smaller diameter toward on the tip side; and at the opening part on the base end side in which the force fit pin 56 in the press-in hole 64 of the cover plate member 42 is inserted, an opening inclined plane 66 is provided which becomes a larger diameter toward on the opening side.SELECTED DRAWING: Figure 1
