<P>PROBLEM TO BE SOLVED: To provide a motor in which a percentage occupied by a base board can be reduced and an yield can be enhanced while securing a space for arranging the other component on a brush holder. <P>SOLUTION: A brush 35 contained retractily in a brush holder 30 is provided to come into pressure-contact freely with a commutator 19 fixed at a predetermined position of an armature shaft 14, a base board 40 is fixed at a position opposing a sensor magnet 41 which is fixed at a predetermined position of the armature shaft 14 of the brush holder 30, and a sensor 42 for detecting a variation in the magnetic field of the sensor magnet 41 is fixed to the base board 40. In such a motor 10, a through hole 30c for inserting the armature shaft 14 and the sensor magnet 41 is formed at the center of the brush holder 30, a base board mounting surface 31a is formed in a shape of an L character to copy the profile of the base board 40 in the vicinity of the through hole 30c on the upper surface 31 of the brush holder 30 and the base board 40 is fixed to the base board mounting surface 31a in a shape of the L character in a vertical state. <P>COPYRIGHT: (C)2008,JPO&INPIT |
