PROBLEM TO BE SOLVED: To set a coefficient of vibration of 15 Hz frequency to about 4 N.s/mm, make a dynamic spring constant of about 100 Hz reducible to about 1000 N/mm, as a liquid-sealed body mount, so that a sufficient vibration isolating characteristic can be obtained. SOLUTION: This body mount, having an inner cylinder 1 fixed to one of a body and a frame in a support side, an outer cylinder 2 fixed to the other, a rubber elastic unit 3 interposed between both the inner/outer cylinders 1, 2, two liquid chambers 4a, 4b formed in locations opposed to each other by interposing the inner cylinder 1, and an orifice passage 6 connecting both the liquid chambers, receives a load input of the body in an axial direction. Axial end walls 40a, 40b in both the liquid chambers 4a, 4b are formed of rubber film partly of the rubber elastic unit 3, this rubber film is formed in oblique shape to the axially outer side toward the outer cylinder 2 from a side of the inner cylinder 1. |
