Each pocket of a cage is composed of a pair of axial wall surfaces opposing each other along the axial line of the cage, a pair of circumferential wall surfaces opposing each other along the circumference direction of the cage, and radii linking the axial wall surfaces and circumferential wall surfa
Each pocket of a cage is composed of a pair of axial wall surfaces opposing each other along the axial line of the cage, a pair of circumferential wall surfaces opposing each other along the circumference direction of the cage, and radii linking the axial wall surfaces and circumferential wall surface. A ratio (R/d) of the radius of curvature R of the radii to the diameter d of the torque transmitting balls is set within a range 0.45 R/d 0.62. Also, the circumferential wall surfaces and radii are shaped along an arc having the radius of curvature R. Further, as to the axial wall surfaces, variance in the treatment margin is lessened by applying the grinding, hardened steel cutting, or the like after the heat treatment (carburized hardening and tempering) is applied to the cage.
