Patent ID: 8129879

Claim:
An electric motor having a brush holder formed by a resinous material and integrally with: a holder main body disposed inside a pair of motor housings and retaining a pair of brushes slidably contacting with a commutator; a power-supply connector portion disposed outside the motor housings and connected detachably to an external connector; and a coupling portion provided so as to protrude outside the motor housings from the holder main body and coupling the holder main portion and the connector portion, the motor comprising: a first lead member formed by a metal plate with a conductive property and including: a main body portion embedded into the holder main body, the coupling portion, and the connector portion; a connector side terminal extended from one end of the main body portion and protruding from the connector portion; and a holder-main-body side terminal extended from another end of the main body portion to the axial direction of the commutator and protruding from the holder main body and connected to one of the brushes; and a second lead member formed by a metal plate with a conductive property and including: a main body portion embedded into the holder main body, the coupling portion, and the connector portion alongside of the first lead member; a connector side terminal extended from one end of the main body portion and protruding from the connector portion; and a holder-main-body side terminal extended from another end of the main body portion to the axial direction of the commutator and protruding from the holder main body and connected to the other of the brushes, wherein each of the connector side terminals of the first and second lead members is disposed so as to match its width direction with an axial direction of the commutator and to be mutually aligned in the width direction, each of the main body portions of the first and second lead members is twisted perpendicularly to the connector side terminal with reference to an axis at a base end of the connector portion and the twisted direction of the main body portions is the opposite direction in each other, and disposed in the coupling portion so as to match its thickness direction with the axial direction of the commutator and to be mutually aligned in the width direction, and the brush holder is clamped and fixed to the pair of motor housings, the holder main body comprises: a base wall extending along a plane orthogonal to an axial direction of the commutator, and a pair of element mounting portions which are disposed through the base wall in the axial direction of the commutator, and in which noise prevention elements are respectively inserted.
