Abstract
A fixing structure of the present invention is capable of fixing permanent magnets to an internal peripheral surface of a cylindrical yoke in a short time without producing a positional deviation. The fixing structure has magnet receiving pieces which are projected on the internal peripheral surface of an internal cylinder, and magnet holders each having elastically deformable magnet pressure pieces formed therein, so that permanent magnets are respectively held between the elastically deformed magnet pressure pieces and the magnet receiving pieces and pressed against the side of the magnet receiving pieces in a normal direction due to the elastic restoring force on the magnet pressure pieces. The permanent magnets can thus be integrally fixed to the internal peripheral surface of the internal cylinder.
