<P>PROBLEM TO BE SOLVED: To provide a rotor which is smaller in size, and reliably transfers torque from a rotor core to a shaft. <P>SOLUTION: A rotor core 22 is sandwiched between a first flange 26 disposed at a first shaft 27 and a second flange 28 disposed at a second shaft 29, and a fastening member 31 penetrating through the rotor core 22 is fixed to two flanges 26 and 28. Therefore, a coupling part coupling with the shaft is not necessary on an inner peripheral surface 25 of the rotor core 22, so that thickness increase of the rotor core 22 can be suppressed to enable downsizing of a rotor 20A. And torque generated by rotation of the rotor core 22 is transmitted from the rotor core 22 through the fastening member 31 to the flanges 26 and 28 to rotate the shafts 27 and 29. The torque is reliably transmitted from the rotor core 22 to the shaft without providing the coupling part coupling with the shaft on the inner peripheral surface 25 of the rotor core 22. <P>COPYRIGHT: (C)2013,JPO&INPIT |
