BUSH DEVICE OF VEHICLE SUSPENSION

PROBLEM TO BE SOLVED: To provide a bush device of vehicle suspension, which suppresses increase in the number of components and generation of abnormal noise and which has nonlinear spring characteristics.SOLUTION: The bush device includes: a plate-like projecting piece 21a which is formed on an inner-peripheral surface of an outer cylinder 21 and has an opening part 21b for inserting a supporting shaft part 22; a plate-like stopper part 22a which is formed on an outer-peripheral surface of the supporting shaft part 22 and at a position joined to an end face of an elastic member 23 on one side; and an elastic member 23 which joins a part between the inner-peripheral surface of the outer cylinder 21 and the outer-peripheral surface of the supporting shaft part 22 inserted into the opening part 21b and is structured so that a part of the plate-like projecting piece 21a is disposed to be overlapped, as viewed axially, with a part of a stopper part 21b to keep the elastic member 23 sandwiched between the plate-like projecting piece 21a and the stopper part 22b.
