Abstract
A constant velocity universal joint includes an outer joint member having an opening portion at one end thereof, and an inner joint member configured to transmit torque while allowing angular displacement with respect to the outer joint member through balls. End portions of a boot closing the opening portion of the outer joint member are fastened and fixed to a mounting part of the outer joint member and a mounting part of a shaft extending from the inner joint member. At a part of an outer peripheral surface of the shaft where at least an inner peripheral surface of the boot contacts when the shaft takes an operating angle with respect to the outer joint member, a sliding bearing is arranged to reduce abrasion due to friction caused by relative movement between the outer peripheral surface of the shaft and the inner peripheral surface of the boot.
