PROBLEM TO BE SOLVED: To improve the assembling property of a rotor in relation to a rotary shaft in the structure for fitting the rotary shaft and the rotor to each other. SOLUTION: In the structure for fitting the rotary shaft an the rotor 14 to each other by pressing the rotor 14 into a fitting hole 14a at a fixed position of the rotary shaft, a chamfered part 14b, which is not pressed into for fitting at the fixed position of the rotary shaft, is provided at a fitting starting end of the fitting hole 14a of the rotor 14 except for the minimum diameter part. A taper part 14c to be enlarged toward the minimum diameter part of the chamfered part 14b is formed continuously to the chamfered part 14b. |
