ABSTRACT:
A motor casing is formed in such a way that an outer peripheral surface of an edge portion of an opening of a yoke to which a permanent magnet is fixed is attached on an inner peripheral surface in a tubular peripheral edge portion of an intermediate bracket on which a brush holder is provided. The motor casing obviates the necessity for making the motor casing exceptionally large even when a radially long brush or an axially long permanent magnet is used.
