ABSTRACT:
A tripod member having three trunnions is inserted in an outer ring. A guide block is supported on each of the trunnions so as to be pivotable around the trunnion and is formed with a ball circulation groove at each side thereof. A plurality of balls are accommodated in the ball circulation groove so that part of the balls will protrude diametrically outwards from the ball circulation groove. The outer ring is formed in its inner surface with raceway grooves for guiding the balls in an axial direction. An arcuate ball rolling surface and a ball guide surface are formed at both sides of each raceway groove to guide the balls and prevent them from dropping out, respectively.
