PROBLEM TO BE SOLVED: To fix a rotor shaft better to a rotor core while matching the positions of the shaft centers thereof.SOLUTION: A rotor shaft 40 is arranged so that the position of the shaft center thereof matches the position of the shaft center of a rotor core 30. Protrusions 42a, 42b of the rotor shaft 40 are brought into contact with recesses 32a, 32b of the rotor core 30, respectively, and fixing members 44, 46 are placed between protrusions 42c, 42d of the rotor shaft 40 and the recesses 32c, 32d of the rotor core 30. Consequently, the rotor shaft 40 can be fixed to the rotor core 30 by means of the fixing members 44, 46, while matching the position of the shaft center of the rotor core 30 with the position of the shaft center of the rotor shaft 40. |
