Provided are: a joining structure capable of suitably obtaining joining strength between components which compose the joining structure; and a joining method thereof. For this purpose, a joining structure (1) includes: a shaft member (10) ; and a thin-walled cylindrical member (20) that fits an inner circumferential surface thereof to an outer circumferential surface of the shaft member (10).
The thin-walled cylindrical member (20) has: a first crimped portion (21), in which an axially intermediate portion is reduced in diameter in a radial direction, and is crimped to the shaft member (10); and a second crimped portion (22), in which an end surface (20a) is folded radially inward, and is crimped to the shaft member (10). |
