The present invention relates to a fixing structure between synthetic resins and a commutator bar of a motor. According to the present invention, C-shaped grip parts are separately formed on upper and lower parts of a combination surface of the commutator bar, combined with synthetic resin, which is the opposite surface to a surface of the commutator bar touching a brush of the motor. A protruding part (K-shaped grip part) combined with the synthetic resins is formed between the C-shape grip parts. According to the present invention, since the C-shaped grip parts and the K-shaped grip part hold the synthetic resins on the upper and lower parts of the commutator bar and on the middle part of the commutator bar respectively, combination between the commutator bar and the synthetic resins becomes strong, thereby reducing a noise of the motor. |
