Claims

[Claims for Utility Model Registration] (1) It has a cylindrical shape with one end open, and the inner periphery of the opening end forming the opening has a large diameter, and has an opening with a ring groove on the inner periphery of the opening end, and has a cylinder shape on the inner periphery. an outer joint member having a cylindrical inner periphery and a plurality of first guide grooves extending in the axial direction on the cylindrical inner periphery; an inner joint member having a second guide groove extending in the axial direction; a ball disposed between the first and second guide grooves for transmitting torque; and a ball holding the ball between the inner and outer joint members. In a constant velocity joint comprising an interposed cage, the outer joint member has a tapered inner periphery whose inner diameter increases toward an opening formed between the cylindrical inner periphery and the open end inner periphery. and a chamfered portion formed in an R shape at a corner where the tapered inner circumference and the cylindrical inner circumference intersect, and extending from the surface of the tapered inner circumference to the surface of the cylindrical inner circumference. A constant velocity joint characterized by being hardened. (2) A ring that has a cylindrical shape with a cylindrical inner periphery that is open at one end, has a plurality of first guide grooves that extend in the axial direction on the cylindrical inner periphery, and that goes around once in the circumferential direction on the inner periphery near the open end. an outer joint member having a groove and having at least a surface portion of the first guide groove hardened; and an outer joint member disposed coaxially with the outer joint member and having the same number of shafts as the first guide grooves on the outer periphery. an inner joint member having a second guide groove extending in the direction; a ball disposed between the first and second guide grooves and transmitting torque; and an inner joint member holding the ball and interposed between the inner and outer joint members. In the constant velocity joint, the ring groove of the outer joint member has a groove bottom diameter larger than the diameter of the inner circumferential surface and the same as or smaller than the groove bottom diameter of the first guide groove. A constant velocity joint characterized by being formed in a range smaller than that.
