Abstract
A fixed type constant velocity universal joint () includes an outer joint member (), an inner joint member (), eight balls (), and a cage (). A diameter (D) of the outer joint member () at an opening end of an inner peripheral surface () is set larger than an outer diameter (D) of the cage () at a center portion in a circumferential direction of pockets () when the cage () is seen from an axial direction of the joint. A bottom surface () of a mouth section () of the outer joint member () is arranged so as to interfere with an imaginary spherical surface (Q) being an extension of the inner peripheral surface () of the outer joint member () toward a deep-side.
