PROBLEM TO BE SOLVED: To provide a method for plastically connecting a driving component, which method can secure the quality of a connected component at a low manufacturing cost. SOLUTION: The inner flange 4 of a hub 1 is pressed against respective projecting portions 8 formed on the outer flange 7 of a shaft 2 by means of a punch 9, and connecting portions 16 are formed on the inner flange 4 by plastically flowing the material of the inner flange 4. Therefore, the respective projecting portions 8 formed on the outer flange 7 are restricted by the inside surfaces of the respective connecting portions 16 of the inner flange 4 of the hub 1 facing to the respective projecting portions 8. By this configuration, the connecting strength of the driving components can be secured, and the driving components having high quality can be achieved. Further, serrations on the connecting surface of the shaft 2 can be omitted, and the manufacturing cost can be greatly reduced. COPYRIGHT: (C)2007,JPO&INPIT
