PROBLEM TO BE SOLVED: To provide a bush capable of reducing inclination of a piston rod to a cylinder in a shock absorber.SOLUTION: A bush is used in a cab suspension including: a support shaft fixed to a rotary member supported to a vehicle frame in a rotatable manner; and a shock absorber having an outer cylinder part provided at an upper end of a piston rod. The bush is arranged between the outer cylinder part and the support shaft inserted into the outer cylinder part. The bush comprises a cylindrical bush body, and a gradually thinned part formed at a portion on a front side in a direction where the support shaft is displaced with rotation of the rotary member from a neutral position, of an end surface in an axis direction of the bush body.SELECTED DRAWING: Figure 5
