<P>PROBLEM TO BE SOLVED: To provide an effective bearing joining structure in place of high-strength bolt joining, and a bearing joining member therefor. Ž<P>SOLUTION: A screw hole (a) is formed in one member A of a joining object, and a drill hole (b) having a diameter larger than its member is formed in the other member B. A screw 2a of a tip of a shaft member 2 is threaded and attached to the screw hole (a), and a mandrel 3 is driven in a driving hole of the shaft member 2, and a bearing piece of its periphery is deformed to the outside, and brought into close contact with an inner surface of the drill hole (b), and both the mutual members are fastened by attaching a nut 4 to a screw 2b of a base end of the shaft member 2 in its state so as to be threaded. Alternatively, the drill hole is formed in both the member of the joining object, and the mandrel is driven in the driving hole of both ends of the shaft member, and the bearing piece of its periphery is deformed to the outside, and bought into close contact with the inner surface of the drill hole, and both the mutual members are fastened by attaching the nut to the screw of both end parts of the shaft member in its state so as to be threaded.
