PURPOSE:To provide a small motor inexpensive and excellent in property by improving the vibration attenuation of a brush arm. CONSTITUTION:In a small-motor comprising a case which has a permanent magnet at the inside periphery, a case cap which is equipped with an input terminal and a brush arm, and a rotor which is equipped with an armature and a commutator and rotates inside the case cap, a damper member 15 is made at the base of the brush arm 7 out of the adhesive material consisting of water aqueous acrylic emulsion made by mixing styrene monomer 5-40wt.% to the main ingredient of butadiene acrylate monomer and polymerizing and reacting them, and adjusting the initial viscosity to 10000-70000cp. |
