1. A rotor of a rotary electric machine comprising:
a shaft having knurled portions formed by knurl processing on an outer peripheral surface of the shaft; and a rotor core having a fitting-recess that is fitted and fixed to the knurled portions of the shaft; wherein, the shaft includes a small diameter portion, which has a diameter smaller than a diameter of the knurled portions, formed on a proximal end of the knurled portions and a flange portion formed on a distal end of the knurled portions; the rotor core includes a small diameter hole, which has a diameter smaller than the diameter of the fitting-recess, formed on a proximal end of the fitting-recess; wherein, when the fitting-recess is fitted into the knurled portions of the shaft, an end face in a distal end of the rotor core abuts the flange portion, while a stepped surface (23) formed between the fitting-recess and the small diameter hole is in a condition of contacting with a stepped surface (13) formed between the knurled portions and the small diameter portion; and a filler is sealed in gaps formed between the knurled portions of the shaft and an internal wall of the fitting-recess of the rotor core. |
