ABSTRACT:
A fan motor having a structure which allows a stopper to keep contact with a thrust plate on a circular contact area only, by inserting a shaft through a sleeve bearing, and by attaching the stopper, against the thrust plate, onto the end portion of the shaft. This assures uniform sliding of the thrust plate against the sleeve bearing without partial contact, even if the stopper is attached in a slight inclination with respect to the thrust plate. Localized wear of the thrust plate and rubbing mechanical noise are thus prevented.
