Claims

[Scope of utility model registration request]

an electric brush that slides into contact with the commutator of the armature; a holding frame that holds the electric brush slidably in the direction of the commutator; one end supported by the commutator and the other end supported by the head of the electric brush; and a first elastic body that applies sliding contact pressure to the electric brush with respect to the commutator, and presses a side surface of the electric brush to press the electric brush against the holding frame. A brush device characterized in that a second elastic body for preventing abnormal vibrations is attached to the holding frame.
