A rotor structure including a rotor, a stator, and magnetic pole parts provided to a rotor core is provided. Each of the magnetic pole parts includes a fixed magnetic-force magnet magnetized in the radial direction, and first variable magnetic-force magnets disposed at both end sides of the fixed magnetic-force magnet in the circumferential direction, respectively. A magnetization sate of each first variable magnetic-force magnet is changeable in the circumferential direction by a given magnetic flux. The first variable magnetic-force magnets are located radially outward of the fixed magnetic-force magnet. A radially outward part of each first variable magnetic-force magnet is held by a respective holding part of the rotor core at a corner part from radially outward. A gap between each holding part and the stator core is wider than a gap between a general outer circumferential surface of the rotor core and the stator core.
