ABSTRACT:
The inlet diameter A of the outer side of a pocket 4a is larger than the diameter Dw of a ball 3 to be housed. The inner side section of the wall surface of the pocket 4a is drawn with a spherical surface 4a1 of the radius R of curvature {the dimension obtained by adding the pocket clearance (corresponding to one side) to the radius (Dw/2) of a ball 3}, the center of curvature of which is made point 0 (the intersection of the pitch circle of the ball 3 and the contact angle line L), the outer side section of the wall surface of the pocket 4a is drawn with a cylindrical surface 4a2 of the radius R of curvature having its center of curvature on the contact angle line L, and the spherical surface 4a1 of the inner side is smoothly continued with the cylindrical surface 4a2 of the outer side.
