摘要：A direct-current motor includes a stator having a magnetic field system, a rotordisposed around the stator, a commutator which rotates together with the rotor, and
power supply brushes which are urged in the axial direction by urging members so as tocome into contact with the sliding contact surfaces. The rotor includes an armature corearound which armature coils are wound, and a rotary shaft which rotates together withthe armature core. The commutator has segments extending radially. The segments havesliding contact surfaces orthogonal to an axial line of the rotary shaft. At least a part ofeach power supply brush comes into contact with the sliding contact surface at a positionfurther radially outward than the armature coil.
