摘要:
A fixed type constant velocity universal joint has track grooves of an outer joint member including first and second track groove portions located on depth and opening sides, respectively. The first track groove portions each have a circular-arc part having a curvature center that is not offset in an axial direction with respect to a joint center, are inclined in a circumferential direction with respect to a joint axial line, and are adjacent to each other in the circumferential direction with their inclination directions opposite to each other. The second track groove portions have a different shape than the first track groove portions to increase an effective track length with respect to a maximum operating angle. The first and second track groove portions are connected respectively to each other on the opening side with respect to the joint center.
