ABSTRACT:
A bushing assembly for use in a suspension of an automotive vehicle. The bushing assembly is comprised of inner and outer cylinder members which are coaxial and spaced from each other. An elastic member and a rigid sleeve member are disposed between the inner and outer cylinder members. A sliding member is disposed between the inner cylinder member and the rigid sleeve member in order to reduce torsion spring effect of the elastic member. The sliding member is prevented from its axial displacement upon contacting with a radially outwardly extending retainer section formed in the inner cylinder member. Additionally, a generally cap-shaped seal rubber is provided to accomplish seal between the end section of the rigid sleeve member and the end section of the inner cylinder member. The seal rubber is located outside the inner cylinder member retainer section and spaced from the outer peripheral part of the inner cylinder member retainer section, thereby reducing resistance in relative rotation between the inner and outer cylinder members maintaining effective seal.
