Claims

[Scope of utility model registration request]

an outer member provided with a cylindrical hole provided with a linear guide groove; and an outer member provided with a groove that cooperates with the guide groove of the outer member to form a ball track, and at least a portion of which is partially spherical. an inner member having a surface, torque transmission balls arranged in each of the grooves, a ball pocket for accommodating the torque transmission balls, and a cylindrical hole of the outer member and a partial spherical surface of the inner member. In a constant velocity universal joint consisting of a retainer having partially spherical inner and outer surfaces with a center of curvature arranged on the joint axis and shifted by an equal amount on both sides of the ball center line on the joint axis, A predetermined spherical gap is formed between the inner surface of the container and the outer surface of the inner member at the center of the outer surface of the inner member, and axial displacement of the inner member is allowed in areas other than the center. 1. A constant velocity universal joint characterized in that an axial clearance is formed between the torque transmitting balls and the ball pockets of the retainer, and a pocket clearance of 5 to 50 μm is provided between the torque transmission balls and the ball pockets of the retainer.
