Claims

[Scope of Claim for Utility Model Registration] (1) A brush device equipped with a terminal connection fitting is installed by inserting the brush device from the radial direction into a frame housing a stator to which a terminal block is attached; In a commutator motor in which the terminal connection fitting is connected to a connection terminal that is attached to the terminal block and to which the end of the stator winding is connected by mounting, the rear end of the brush holder provided in the brush device. A replacement brush unit is provided on both sides of the brush holder, and a pair of engaging part receivers are formed that can be engaged with the engaging parts on both sides of the brush cap metal fitting provided to cover the rear surface of the brush holder. The terminal connecting fitting to be attached is connected to a terminal engaging portion electrically connected to the connecting terminal, and the terminal engaging portion is bent at a substantially right angle to the rear end of the terminal engaging portion, and is connected to the terminal engaging portion electrically connected to the connecting terminal. a brush connecting portion that can be broken and removed on the side of the bent portion, and the brush connecting portion is independently bent at a substantially right angle to the rear end of the terminal engaging portion and is connected to the brush connecting portion; A commutator motor characterized in that it is formed from a preliminary connection part that comes into contact with a cap metal fitting and is electrically connected. (2) The commutator motor as set forth in claim (1) of the utility model registration, characterized in that the preliminary connection portion is provided with a gap formed between it and the rear surface of the brush holder.
