Abstract
A fixed type constant velocity universal joint is capable of reducing the size and weight of a cage while keeping the strength of the cage, and is also capable of improving the high angle strength and the durability. An offset angle θof the cage, which is defined by lines that connect a center curvature of an inner spherical surface and a center curvature of an outer spherical surface of the cage and centers of torque transmission balls, and a line that connects the centers of the torque transmission balls and a joint center in a state where a joint operating angle is 0°, is set in a range of 2.7°≦θ<5.7°.
