<P>PROBLEM TO BE SOLVED: To provide a composite member in which a first member can be accurately and strongly fixed to a second member, the composite member being configured by making the second member penetrate the through hole of the first member, so that the first member can be fixed to the second member, and a method of manufacturing the composite member. <P>SOLUTION: According to a method, in a first member 11, a through hole 13 larger than a second member 12 is provided and the second member 12 is made to penetrate the through hole 13. By iteratively generating shearing stress while generating compression stress in the second member 12 within the through hole 13, the second member 12 is partially thickened and by bringing the thickened portion of the second member 12 into pressure-contact with the through hole 13, the first member 11 is fixed to the periphery of the second member 12. A small diameter hole portion 23, a large diameter hole portion 24, and an annular hole inner surface step portion 26 between the small diameter hole portion 23 and the large diameter hole portion 24 are provided in the through hole 13. The second member 12 includes a small diameter shaft portion 33, a large diameter shaft portion 34 and an annular shaft outer surface step portion 22 opposed to the hole inner surface step portion 21 between the small diameter shaft portion 33 and the large diameter shaft portion 34. While bringing the hole inner surface step portion 21 into pressure-contact with the shaft outer surface step portion 22, the second member 12 is thickened. <P>COPYRIGHT: (C)2013,JPO&INPIT |
