<P>PROBLEM TO BE SOLVED: To provide a rotator of an electromotor in which it is possible to surely fix, in a simple way, an insulation sleeve to be given to a shaft, which electrically insulates a roll bearing from the shaft, in order to constrain electric corrosion in the roll bearing. <P>SOLUTION: In the rotator of the electromotor of this invention, a magnet and shaft of the rotator are integrated using a resin part, and roll bearings are disposed in both end faces in the axial direction of the resin part formed in the outer periphery of the shaft. The rotator of the electromotor comprises: an insulation sleeve which is provided between at least one of the roll bearings and the shaft and in which the roll bearing and the shaft are integrated using a resin part, and a plurality of convex parts which are formed in the neighborhood of the end face on the side being embedded in the resign part of the insulation sleeve in an circumferential direction at a substantially equal interval and each of which has the apex in the neighborhood of the end face. <P>COPYRIGHT: (C)2012,JPO&INPIT |
