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 d24 of the apex of the convex sections 24a, 24b is equal to or less than the inner diameter R15 of circular holes 15, and the outer diameter D23 of the flange sections 23a, 23b is equal to or greater than the outer diameter D24 of the bottom section of the convex sections 24a, 24b. Furthermore, the amount of protrusion L23 that the flange sections 23a, 23b protrude from the convex sections 24a, 24b is equal to or less than two times the thickness T23 in the axial direction of the flange sections 23a, 23b.

摘要: In a manufacturing process of a corrugated cage, an intermediate assembly 17a is configured by press-fitting each of press-fitting portions 24 and 24 respectively provided in base end portions of rod portions 13b and 13b of rivets 9b and 9b into each of through-holes 12a and 12a of a cage element 8a on one side, and nitriding treatment is performed on the intermediate assembly 17a. An axial dimension X of each of the press-fitting portions 24 and 24 is made smaller than an axial dimension Y of each of the through-holes 12a and 12a (X

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 d24 of the apex of the convex sections 24a, 24b is equal to or less than the inner diameter R15 of circular holes 15, and the outer diameter D23 of the flange sections 23a, 23b is equal to or greater than the outer diameter D24 of the bottom section of the convex sections 24a, 24b.
