PROBLEM TO BE SOLVED: To provide a liquid sealed bush by which high performance such as improvement of riding comfort or operational stability is attained.SOLUTION: A liquid sealed bush 1 comprises an inner cylinder 11 and an outer member 12. The outer member 12 defines a pair of liquid chambers between it and the inner cylinder 11, and has an orifice part 13 formed with an orifice passage 24 communicating the liquid chambers to each other. There is provided an elastic body 14 for elastically connecting the orifice part 13 with the inner cylinder 11. The pair of liquid chambers are arranged individually at both sides holding the inner cylinder 11. The inner cylinder 11 is formed with a first protrusion part 11a protruded outside in a radial direction and fitted into the elastic body, and the orifice part 13 is formed with a second protrusion part 28 protruded inward in a radial direction and fitted into the elastic body 14. The first protrusion part 11a and the second protrusion part 28 are arranged at both of the pair of adjoining liquid chambers in their peripheral direction while their peripheral positions are coincided with each other and their central axis positions are made different from each other.SELECTED DRAWING: Figure 3 |
