PURPOSE:To improve damping function of horizontal vibration for a suspension device of a trailing link installing car, by forming a bush on the car body mounting side of the trailing link, out of liquid sealed bush for which plural liquid chambers are communicated with each other so as to generate different damping forces to horizontal input. CONSTITUTION:A bush 4 with which a trailing link 3 is mounted on a car body 5 is formed as a liquid sealed bush for which plural liquid chambers 9, 10 are communicated with each other by a communicating route 11, whose front end diameter da is defined larger than the rear end diameter db, and is formed into an orifice with its middle part as a gradual taper, so as to generate different damping forces in horizontal direction. In this structure, horizontal vibration can be effectively damped. |
