Abstract
A rotor includes a shaft having knurled portions and a rotor core having a fitting-recess that is fitted and fixed to the knurled portions. The shaft has a small diameter portion on one end of the knurled portions and a flange portion on another end. The rotor core has a small diameter hole on one end of the fitting-recess. When the fitting-recess is fitted into the knurled portions, an end face in the other end of the rotor core abuts the flange portion, while a stepped surface between the fitting-recess and the small diameter hole contacts with an end face in the one end of the knurled portions. Thus, a filler is sealed in gaps formed between the knurled portions and an internal wall of the fitting-recess.
