Abstract

PURPOSE:To avoid exfoliation of a brush plate and a bonding layer by making the rigidity of a tape in the compressing direction to a commutator surface small and making the rigidity of the tape in the direction perpendicular to the former direction large, and applying the vibration-proof tape an a brush plate. CONSTITUTION:A bonding layer 13 is provided on the back of a tape material 12, and a plurality of lateral (Y direction) notches 14 are formed on the upper surface. In this case, the compressing direction to a brush is assumed to be the Z direction, and the rigidity in this direction is small. Therefore the tape material is easy to bent in this direction. The rigidity in the direction (the Y direction) perpendicular to the Z direction is large, and the tape material is hard to bent. A brush 7 is formed by applying this vibration-proof tape on a brush plate 15. Since a plurality of notches 14 are provided on the vibration-proof tape, the bending force in the Z-direction is not affected, and the exfoliation of the brush plate 15 and the bonding layer 13 is not caused.
