Abstract
A mandrel formed of urethane is inserted into a hollow shaft and is compressed axially by a die and a pad. The shaft is then fit in a shaft through hole of a rotor core. Thereafter, compression of the mandrel is released or reduced, and the mandrel is removed from the shaft. Thus, in fitting the hollow shaft in the shaft through hole of the rotor core, deformation of the shaft is reduced.
