Fixed constant velocity universal joint
An outer joint member has first and second track groove portions located respectively on depth and opening sides. The first track groove portions each have a circular-arc ball-raceway center line having a curvature center that is not offset in an axial direction with respect to a joint center. The second track groove portions each have a ball-raceway center line including a straight part to increase an effective track length at a maximum operating angle. Track grooves of an inner joint member each have a ball-raceway center line that is mirror-image symmetrical with a ball-raceway center line of the paired track groove of the outer joint member with respect to a plane passing through the joint center at an operating angle of 0°.
