Claims

[Claims for Utility Model Registration] An outer joint member that is cup-shaped and has a spherical inner circumference and a plurality of first guide grooves extending in an arc shape in the axial direction; an inner joint member having second guide grooves extending in the same number as the first guide grooves; a cage fitted to both the inner and outer joint members; engaging with the second guide groove;
a ball that transmits the torque of the outer joint member to the inner joint member, and the center of curvature of the groove center line extending in an arc shape in the axial direction of the first and second guide grooves is on both sides of the joint center plane. In the eccentric constant velocity joint, the center of curvature of the first guide groove is on the opposite side beyond the axis on a first plane including the groove center line and the axis, and between a line of intersection formed by a second plane including the cup-shaped opening end of the joint member and the first plane, and a line of intersection formed by the center plane of the joint and the first plane; A constant velocity joint characterized by:
