ない。2. Description of the Related Art Conventionally, there are some metal brushes that come into contact with a commutator to which a vibration damping rubber is attached for damping the brush. However, the vibration damping effect is not sufficient, and the elasticity of the adhesive decreases especially at high temperatures. In some cases, the vibration damping of the brush is insufficient due to the decrease in elasticity of the foamed rubber used as the anti-vibration rubber, or the damping effect is insufficient due to the increase of the elastic coefficient due to the curing of the anti-vibration rubber at low temperature. In terms of vibration damping, when operating in a polyhydric alcohol gas atmosphere, the sliding of the metal contacts is gas lubricated and the vibration damping effect is not sufficient.

フテストによりブラシ・整流子の摩耗，初期特性のうち
主に無負荷電流値，無負荷騒音値の測定で判定した。In the vibration damping material of the present invention, since the nonwoven fabric and the film are welded, and the flocking and the film are fixed to each other, the base material of the film does not shift, and the vibration damping property is optimized, and the vibration damping property is low Both the vibration damping property and the vibration damping property at high temperature are superior to the conventional foamed rubber in the vibration damping effect of the brush. Therefore, it is difficult to obtain the characteristics of a small motor from low temperature to high temperature (-30 ℃
(-+ 60 ° C) Motor rotation variation and brush / commutator wear have been reduced over a wide range. The damping property was judged by measuring the wear of the brush / commutator and the no-load current value and no-load noise value among the initial characteristics in the motor life test.
