Direct-current commutator motor

A direct-current commutator motor comprising:

• 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 the commutator to come into contact with the terminal section, is supported by the stator section and relatively rotates with respect to the commutator;
• and
• a pigtail provided on the brush to transmit an electric current supplied from the outside to the brush,
• wherein the brush is provided with a hollow section extending along a direction in which a rotary shaft of the rotor section extends,
• the brush is provided with a different material portion formed of a material different from the material forming the brush at an end portion opposite to an end portion on a side facing the commutator, and
• the hollow section and the different material portion are provided at intervals in a direction in which the brush is pressed toward the commutator.
