摘要： A fixed type constant velocity universal joint secures smooth rotation and reduces a load on a cage even at a large operating angle and when bearing large torque. The universal joint includes an outer joint member having an inner spherical surface in which track grooves are circumferentially formed in an axial direction and an inner joint member having an outer spherical surface in which track grooves paired with the track grooves of the outer joint member are circumferentially formed in the axial direction and multiple outer spherical surface portions circumferentially arranged. Balls are interposed between the track grooves of the outer and inner joint members for transmitting torque. A cage is interposed between the inner spherical surface and the outer spherical surface for retaining the balls. A spherical surface angle of the outer spherical surface on a joint opening side is set to 12.5° or more.
