Document Type and Number:
WIPO Patent Application WO/2015/137044
Kind Code:
A1
Abstract:
A crimped structure wherein an inside member and an outside member arranged on the outside of the inside member are joined to each other. The inside member includes an insertion section (17) having a cylindrical outer circumferential surface (17S), and a recessed section (17U) provided in the outer circumferential surface (17S). The outside member includes: a tubular part (24) forming an opening (24K) into which the insertion part (17) is inserted; a reduced-diameter section (21), which is formed in the tubular part (24) and has a plastically deformed shape such that the diameter is annularly reduced toward the inside in the radial direction; and protruding sections (22) having a plastically deformed shape such that a portion thereof in the circumferential direction of the reduced-diameter section (21) intrudes into the recessed section (17U). Thus, relative rotation of the inside member and the outside member is inhibited.
