ABSTRACT:
A tripod type constant velocity universal joint for interconnecting two shafts to permit transmission of a driving force in a vehicle such as a motor car. In said tripod type constant velocity universal joint, a trunnion portion of the tripod shafts is urged against and supported by a tulip portion of a second shaft by a tripod spring, the spherical head of a mushroom-shaped member provided in the mounting hole of said trunnion portion is kept in contact with a recess in said tulip portion by the biasing force of a compression spring, and further, said mushroom-shaped member or said trunnion portion of the tripod shafts is formed to provide a spherically curved surface or a conical surface incorporating a straight line, in which the distance from the center of the joint is increased as a point on the external configuration leaves the center toward the outer periphery.
