ABSTRACT:
A rotatable rotor 41 and a stator 51 located at a predetermined gap between outer circumferential face of the rotor 41 provided with half-cylindrical inner circumferential face are provided. The both ends of the outer circumferential face of the rotor 41 are provided with a step portion 44 to retain a predetermined gap between the opposing faces of the rotor 41 and the stator 51, and a stopper portion 45 to be abutted to both end faces of the stator in the axial direction. A forcing means 61(plate spring) are also provided to force the stator 51 to the rotor 41 so that the inner circumferential face of the stator is abutted at the step portion 44.
