Claims

[Scope of Claim for Utility Model Registration] (1) Constant velocity universal joint consisting of the following: (a) An inner ring having a cylindrical outer diameter surface and with ball tracks formed at equidistant positions on the circumference of this outer diameter surface; (b) An outer ring having a cylindrical inner diameter surface and with ball tracks formed at equidistant positions on the circumference of this inner diameter surface; (c) Transmission balls interposed between the ball tracks of the inner ring and the ball tracks of the outer ring; (d) Inner and outer rings In between, ball pockets having a cylindrical inner diameter surface and a cylindrical outer diameter surface are formed at equidistant positions on the circumference and penetrated in the radial direction for accommodating torque transmission balls, and A first annular protrusion is formed on the inner diameter surface of one end at a position equidistant in the axial direction from the axial center of the ball pocket, and a second annular protrusion is formed on the outer diameter surface of the other end. A cage. (2) The constant velocity universal joint according to claim 1, wherein the ball track of the inner ring and the ball track of the outer ring are parallel to each other and extend in the axial direction. (3) The constant velocity universal joint according to claim 1, wherein the ball track of the inner ring and the ball track of the outer ring intersect with each other in the circumferential direction. (4) The constant velocity universal joint according to claim 1, wherein the ball track of the inner ring and the ball track of the outer ring intersect with each other in the radial direction. (5) The constant velocity universal joint according to claim 4, wherein the ball track of the inner ring and the ball track of the outer ring form an arc whose center of curvature is a point equidistant from each other from the joint axis on the joint axis.
