ABSTRACT:
Fixed members of the small-sized motor centrifugal governor switch and commutator segment metals are secured to a boss of a molding insulating resin mounted on a shaft of the rotor, thereby disposing the centrifugal governor switch on the same side as the commutator with respect to the rotor. With this construction, there is no need of installing the centrifugal governor switch in the space radially centrally of the stator magnet, hence there is no need of restricting the size of the centrifugal governor switch to be smaller than the inner diameter of the stator magnet. Accordingly the centrifugal governor switch can be made larger, thereby securing a better function.
