Abstract
A flat motor is disclosed comprising a motor housing having a first engaging mechanism, a magnet fixed to the motor housing, a holder plate attached to the motor housing and provided with a pair of brush holders. The holder plate has a second engaging mechanism engaging the first engaging mechanism. A third engaging mechanism engages an inside surface of the magnet. The holder plate can be positioned coaxially with the motor housing by the engagement of the first engaging mechanism with the second engaging mechanism, the magnet can be positioned coaxially with the holder plate by the engagement of the third engaging mechanism with the magnet. The motor housing, the holder plate and the magnet can all be positioned coaxially with one another without use of a particular jig, thereby improving the assembly of the flat motor and increasing the productivity of the motor.
