ABSTRACT:
An object of the invention is to improve a layout property of members arranged on the brush holder. Power feeding terminals are formed in a flat shape extending in an axial direction of an armature shaft, and the power feeding terminal is arranged side by side in a width direction with respect to the power feeding terminal in one end portion of a brush holder. A condenser is provided between the power feeding terminals and the armature shaft. Further, a power supply circuit for electrically connecting the power feeding terminals to a leaf spring brush is electrically connected to a motor housing via a grounding stay, and a choke coil for reducing a noise generated in the power supply circuit is arranged so as to be lapped over a screw member fixing the leaf spring brush to the brush holder in the axial direction of the armature shaft.
