Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a technique for firmly fastening a member having a hole with a member having a columnar part. SOLUTION: This set member is formed by fastening a first member 14 having the hole with a second member 12 having the columnar part. In the set member, the hardness of the fastening surface of one of the first member 14 and the second member 12 is higher than that of the fastening surface of the other member, and the fastening surface of the member having higher hardness is provided with projections 16 extending in the axial direction and repeatedly formed in the circumferential direction. The height of crest of the projection 16 is lower at one end part in the axial direction of the fastening surface, and higher at the other end in the axial direction of the fastening surface to be continuous from one end part to the other end part. The member having a lower hardness is provided with a plastic flow part flowing in the space between the projections 16 of the member having the higher hardness by plastic flow in the axial direction and in the circumferential direction.
