Abstract
A rotor is provided with a rotor core, a shaft fastening hole provided at the center of the rotor core, and magnets provided to the outer circumferential portion of the rotor core. Circular arc slits are formed at intervals on double concentric circles, respectively, so as to be located around the shaft fastening hole of the rotor core. The slits are arranged in such a manner that the outside slits on the outer circle are each located so as to block the portions located in the intervals between adjacent inside slits on the inner circle.
