Abstract:
PROBLEM TO BE SOLVED: To reduce the generation stress of a shock absorber for a vehicle, and to improve static strength and fatigue strength.SOLUTION: This shock absorber for a vehicle comprises: a rod; an inner cylinder part; an outer cylinder part for accommodating the inner cylinder part; a connecting part for connecting the inner cylinder part and the outer cylinder part; and a fixing part for fixing the shock absorber for the vehicle to a wheel support member. A virtual line passing a center point having a circular shape in a cross section of the inner cylinder part out of a virtual line which is parallel with a linear progressing direction of the vehicle is designated as a first virtual line, and the connecting part has first and second connecting parts which are formed at two portions of the inner cylinder part overlapped on the first virtual line, and third and fourth connecting parts which are formed at a portion of the inner cylinder part which is not overlapped on the first virtual line. The fourth connecting part is arranged at a side approximate to the fixing part rather than the third connecting part, a length of the first connecting part in a peripheral direction and a length of the second connecting part in the peripheral direction are longer than a length of the third connecting part in the peripheral direction, and the length of the third connecting part in the peripheral direction is longer than a length of the fourth connecting part in the peripheral direction.SELECTED DRAWING: Figure 2
