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.
