Claims

[Scope of utility model registration request]

An outer ring with multiple axial grooves formed on the inner diameter surface,
The inner ring has a plurality of grooves on its outer diameter surface that form a ball track with the grooves on the outer ring, and the inner ring has a partially spherical surface formed on a part of its outer diameter surface, and the grooves on the inner ring and the outer ring form the inner ring. It has a torque transmission ball that is rotatably incorporated into a ball track and a pocket that accommodates the ball, and a spherical surface that engages with the inner diameter surface of the outer ring and the partial spherical surface of the inner ring, respectively. In a double offset type constant velocity joint, the center of the outer spherical outer diameter surface and the inner spherical surface of the cage is shifted from the ball pocket center line by an equal distance to the left and right on the joint center line. A double offset type constant velocity joint, characterized in that a flat portion is formed on the outer diameter of the cage, and the inner diameter of the cage is slightly smaller than the inner diameter of the large end surface of the cage.
