構造としたことを特徴とする直流機用ブラシホルダ。A spring supported by a bracket of a DC machine case to slidably hold the brush inside and press the other end of the brush so that one end of the brush comes into contact with the commutator surface; A brush holder consisting of a box-shaped body with two open sides holding therein a pigtail that serves as a power supply end to the brush and electrically connects a metal terminal plate that abuts one end of the spring. It is a box-shaped body made of aluminum, and the two opposing sides of this box-shaped body are shaped like a U-shape.
A terminal plate having a shape that can be sandwiched between the U-shaped terminal plates is made of an elastic metal plate, and hook-shaped claws are provided on each of the two sides thereof to protrude outward, and the above-mentioned hook-shaped claws and the hook-shaped claws are provided on the side of the U-shaped terminal plate. An elastic plate made of an insulating material that has an engagement hole that allows the terminal block to be locked to the brush holder by simply inserting the terminal block, and the both ends of the plate are supported by grooves provided in the bracket. A brush holder for a DC machine, characterized in that the terminal plate is pressed through a lead wire arranged on the surface of the terminal plate.
