Document Type and Number:
WIPO Patent Application WO/2011/118219
Kind Code:
A1
Abstract:
Disclosed is a metal component coupling structure and metal component coupling device capable of high strength and high precision coupling. An axial part (17) of a second metal component (12) is fitted in an annular part (14) of a first metal component (11), a restraint ring (33) is arranged on the outer circumference of the annular part (14) of the first metal component (11), and, by plastically deforming by applying force to the annular part (14), said annular part (14) is made to enter into a coupling groove (16) of the axial part (17), coupling the first metal component (11) and the second metal component (12) by mechanical interlocking.
