A constant velocity joint includes balls each rollably supported by an associated one of outer ball grooves and an associated one of inner ball grooves facing each other such that the inclined direction of the associated outer ball groove relative to a central axis of an outer joint member is opposite to the inclined direction of the associated inner ball groove relative to a central axis of an inner joint member. The inner joint member includes escape portions to allow escape of the balls from the inner ball grooves to a first side of the central axis of the inner joint member. Each of the escape portions is provided at least between an end face at the first side of the central axis of the inner joint member and a first rolling guide lateral surface of the associated inner ball groove that forms an acute angle with the end face.
