Abstract
A brush device for a miniature electric motor of a type, wherein the commutator brush is inserted into a brush holding member made of a leaf spring which is generally bent in the form of a letter 'L', one side of which is in a slightly bent form at about the middle portion thereof with a brush fitting portion being provided at the extreme end thereof, and the other side of which is rectilinear with a fitting portion to the main body of the motor being provided at the extreme end thereof. The brush fitting section has a pair of brush holding flaps which are mutually opposed along the lengthwise direction of the holder, and formed by inwardly bending from the flat surface part of the holder, a brush inserting guide section, and a slip-preventive member to prevent the brush from slipping out in the direction of its insertion; the slightly bent portion of the brush holder is provided with reinforcing means to hold the slightly bent portion in its original shape; and the brush per se has a head section to be inserted between the pair of flaps on the holder.
