ABSTRACT:
A torsion spring received in a recess in an inner joint member is engaged at one end thereof with an engaging groove in a cage and at the other end with the wall surface of the recess, thereby constantly urging the cage against the inner joint member. As a result, a torque transmitting ball received in the pocket of the cage is elastically pressed against the narrow side (open side) of the wedge of the ball track by the cage, whereby the circumferential clearance between the guide groove and the torque transmitting ball disappears, preventing the rotation backlash of the joint.
