Abstract
A direct-current commutator motor includes a stator section having a magnet; a rotor section which is rotatably provided in the stator section and has a coil configured to generate a magnetic field by being energized; a commutator which has a plurality of terminal sections provided on an outer circumferential surface at intervals in a circumferential direction and rotates together with the rotor section to energize the coil; a brush which is pressed against and comes into contact with the commutator, is supported by the stator section, and relatively rotates with respect to the commutator; and a pigtail provided in the brush to transmit an electric current supplied from the outside to the brush. The brush is provided with a through-hole extending along a direction in which a rotary shaft of the rotor section extends.
