摘要:
Provided is a fixed type constant velocity universal joint, in which: each of first track groove portions positioned on an interior side of an outer joint member includes an arc part having a curvature center that is positioned without being offset in an axial direction with respect to a joint center; the first track groove portions are inclined in a peripheral direction with respect to a joint axial line (N-N) and adjacent to each other in the peripheral direction with their inclination directions opposite to each other; each of second track groove portions positioned on an opening side is formed into a different shape from a shape of the each of the first track groove portions so as to increase an effective track length at a maximum operating angle; the each of the first track groove portions and the each of the second track groove portions are connected to each other at a position on the opening side with respect to the joint center; each of track grooves of an inner joint member is formed so as to be mirror-image symmetrical with corresponding one of paired track grooves of the outer joint member with respect to a plane including the joint center and being perpendicular to the joint axial line at an operating angle of 0°; and an axial clearance between the inner joint member and a cage is set to be larger than an axial clearance corresponding to a clearance between each of balls and each of the track grooves.
