Title:
COUPLING STRUCTURE AND METHOD FOR MANUFACTURING COUPLING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/202645
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a coupling structure of two members obtained by spinning, said coupling structure having excellent coupling force with respect to stress in the rotation direction. In order to solve this problem, provided is a coupling structure of a first member and a tubular second member that is coupled to the first member while the first member is arranged in the interior of the second member, said coupling structure characterized in that a recessed section or a protruding section that is intermittent or continuous in the axial direction is formed on the outside of the first member, and the second member is subjected to a spinning process while the second member covers the recessed section or protruding section of the first member, thereby coupling the first member and the second member so as to prevent relative rotation in the circumferential direction. Thus, it is possible to provide a coupling structure of two members obtained by spinning, said coupling structure having excellent coupling force with respect to stress in the rotation direction.
