BUSH DEVICE OF SUSPENSION FOR VEHICLE

PROBLEM TO BE SOLVED: To provide a bush member of a suspension for a vehicle which does not generate noise and is suppressed in a variation of an increase amount of a roll steer.SOLUTION: The bush device of the suspension for the vehicle comprises an outer cylinder 21, a support shaft 22 and an elastic member 23. The support shaft 22 comprises a stopper 22a which is arranged at the external peripheral face outside the vehicle in the axial direction rather than the outer cylinder 21 so as to protrude along the circumferential direction, and formed in a range of a semi-circle at the lower side of the vehicle. The outer cylinder 21 comprises a flange 21a which is arranged at the end edge outside the vehicle in the axial direction so as to protrude to the outside of the radial direction along the circumferential direction. The elastic member 23 has a swelling part 23a which is extended to the outside of the vehicle in the axial direction rather than the flange 21a, swollen to the outside of the radial direction in the range of the semi-circle at the lower side of the vehicle along the flange 21a, and connected to the stopper 22a and the flange 21a.
