Abstract
The apparatus prevents the unintentional removal of a universal joint of the type where a tubular outer member is provided on an end portion of a shaft. In this structure, plural longitudinal directional sliding grooves are arranged in parallel one with another and an inner member provided on an end portion of another shaft is provided with plural spherical surface members. These may be spherical surface rollers, balls or the like. The respective spherical surface members are in slidable engagement with associated sliding grooves. An open end of the outer member has an annular closure member and is provided with concave portions facing the respective spherical surface members in the sliding grooves. The inner surfaces are formed into spherical surfaces substantially in conformity with the spherical surfaces of the spherical surface members.
