る。The shaft is made of synthetic resin or aluminum. The former synthetic resin shaft, which is molded by an injection molding machine, uses the molding machine or a means to project with a round cross-section / fixed type protruding rod, so the shaft length is only 50 mm to 60 mm. I can't make it. For this reason, in order to use it as the rotary brush shaft, a means is used in which about 50 mm to 60 mm shafts are combined with about three metal pins or the like to have a length of about 150 mm. Without using such a means, if a long shaft with a length of 150 mm or more is made with a protruding rod, it may not be possible to perform extrusion processing if the shaft has poor shrinkage or mold release. It tended to be extremely high. Further, in the case of a shaft having poor contraction, there is a problem that the shaft is warped.
