JOINT STRUCTURE, AND JOINING METHOD THEREFOR

摘要

The purpose of the present invention is to provide: a joint structure with which members configuring the joint structure can be suitably joined; and a joining method therefor. Accordingly, a joint structure (1) is provided with: a shaft member (10); and a cylindrical member (20) which has an inner peripheral surface thereof fitted to an outer peripheral surface of the shaft member (10). The cylindrical member (20) is provided with: a first press-joined portion (21) which is press-joined along axial-direction grooves (11) provided to the shaft member (10) in an axial direction; and a second press-joined portion (22) which engages with the axial-direction grooves (11), and which is press-joined along a peripheral-direction groove (12) provided to a peripheral surface of the shaft member (10) by radially reducing the diameter of an intermediate portion in the axial direction.
