Outer ball grooves of an outer joint member of a constant velocity joint each have a first ball groove for allowing a ball to roll therein when the constant velocity joint operates, and a second ball groove having a ball groove radius larger than a ball groove radius of the first ball groove. The second ball groove has a curved line and a connecting line. The curved line is connected to a groove bottom end of the first ball groove located closer to an opening of the outer joint member and is curved radially outward in a concave manner. The connecting line connects the curved line and the opening. The curved line is curved with a curvature center that is located closer to the opening than the groove bottom end of the first ball groove and that is located radially inside the outer joint member.

Constant velocity joint and method of manufacturing the same

A constant velocity joint comprises an outer race, inner race and torque transmitting elements. The outer race has a cylindrical hollow part with an opening at one end and plural walls on an inner surface of the cylindrical hollow part. At the opening of the cylindrical hollow part, the walls have projections formed by a pin-drive. The inner race is assembled with the torque transmitting elements and press-fitted into the cylindrical hollow part of the outer race.
