A rotor core has a regular decagon base portion in its cross section relative to a shaft center and ten convex portions each of which is located between each angle of the regular decagon base portion. Each convex portion has a first convex curve having a single curvature radius. Each permanent magnet is a curved plate and has a concave curve and a second convex curve. Each permanent magnet is provided so that the concave curve adheres on the first convex curve. When each permanent magnet moves in circumferential direction relative to the rotor core, the concave curve slides on the first convex curve of the rotor core. A position of the smallest gap clearance between the second convex curve and the stator does not change. A magnetic-flux-strength maximum position is not changed easily.
