Claims

[Scope of utility model registration request]

A brush holder slidably holds the brush, and a spring housed in the brush holder presses the brush to a commutator on the rotor side, so that the current flowing through the armature coil is transferred to the commutator. and the brush, in which the brush holder is opened at its outer circumferential side, a spring receiver is removably attached to the opening, and a spring that presses the brush is set by the spring receiver. A direct current motor characterized by being designed to receive.
