摘要: Characteristics of joint sections using rivets 11a that join flat sections 12a, 12b of a pair of cage elements are improved regardless of differences in the volumes of the rivets 11a. A head section 16a and a crimped section 19a of a rivet 11a comprise flange sections 23a, 23b and convex sections 24a, 24b The inside surfaces of the flange sections 23a, 23b press against the outside surfaces of the flat sections 12a, 12b. The convex sections 24a, 24b have a truncated cone shape with the maximum diameter being on the flange section 23a, 23b side. The diameter d 24 of the apex of the convex sections 24a, 24b is equal to or less than the inner diameter R 15 of circular holes 15, and the outer diameter D 23 of the flange sections 23a, 23b is equal to or greater than the outer diameter D 24 of the bottom section of the convex sections 24a, 24b Furthermore, the amount of protrusion L 23 that the flange sections 23a, 23b protrude from the convex sections 24a, 24b is equal to or less than two times the thickness T 23 in the axial direction of the flange sections 23a, 23b.
