Abstract

PURPOSE: To make a vibration and shock got by a brush as small as possible and improve the rectification performance of said brush by putting rubber or sponge for absorbing vibration between rigid plastics, forming them into a U-shaped body, and fitting said body to the head of a two-piece brush.
CONSTITUTION: Rubber or sponge 2 for absorbing vibration is held like a sandwich between rigid plastics (synthetic resin) 1 so as to be formed into a U-shaped clip, and an opening in the lower part of said U-shape is made about 2mm narrower than that in the upper part thereof. Also, grooves are cut in a part contacting with the clip in the outside of a two-piece brush 3, so that said grooves become deeper as their position lowers, their depth is about 1mm in the lower place of said clip-contacting part and each groove is tapered in cross section. When said clip is fitted to the upper part of said two-piece brush 3, it is possible to fix the brush, to prevent a damage in the head of said brush and to absorb the vibration and shock thereof.
