Abstract

A manufacturing method for an outer joint member of a constant velocity universal joint includes forming a cup member and a shaft member, forming a joining hole in a thickness of a bottom portion to prepare the cup member as a finished component, and forming a joining outer surface on an end portion of the shaft member to be joined onto the bottom portion of the cup member to prepare the shaft member as a finished component. The method also includes fitting the joining hole of the cup member and the joining outer surface of the shaft member as the finished components to each other, and welding a fitting portion between the joining hole and the joining outer surface through irradiation of a beam from an inner side of the cup member, a diameter of the fitting portion being an equal dimension for each joint size.
