The first track groove portions are inclined in a peripheral direction of the outer joint member with respect to a joint axial line and adjacent to each other in the peripheral direction with their inclination directions opposite to each other. Each of the second track groove portions includes a linear part and is connected to the each of the first track groove portions at a position on the opening side with respect to the joint center. Track grooves of inner and outer joint members are formed to be mirror-image symmetrical with respect to a joint center plane at an operating angle of 0°.
