ABSTRACT:
A toe correction bushing (1) is composed of a main body (2) and a stopper member (3), wherein the main body (2) is integrally provided with an inner cylinder (4), an outer cylinder (5), and an elastic body (6). The outer cylinder (5) is provided at part of the axial end with an outwardly opening inclined section (7). A recessed space (8) is provided inside of the inclined section (7). The stopper member (3) is provided with a circular plate section (20) and a stopper projection (23) at the peripheral section thereof. A boss (21) provided at the central section of the stopper member (3) is press-fitted into one end of the inner cylinder (4) for integration and at the same time, the stopper projection (23) is caused to engage the recessed space (8). When a lateral force F to the right is applied to the outer cylinder (5), the axial movement of the outer cylinder (5) is controlled by the stopper projection (23) and displaced in the direction perpendicular to the axis by an inclined plane (24) for toe correction. It is possible to change characteristics of the toe correction by changing the material, shape or the like of the stopper projection (23).
