ABSTRACT:
A joining structure comprises a shaft made of metal and a disc of metal more reducible than the shaft. The shaft has arcuate walls defined by a basic circle, and a plurality of projections each projecting from the basic circle and extending along the axis of the basic circle. The projections are spaced from each other so that the arcuate walls are disposed all between the projections. The disc has a hole of the same diameter as the basic circle. The shaft is forcedly inserted into the hole of the disc so that the projections cut into the disc to be rigidly joined to the disc with high concentricity between the shaft and the hole.
