てなるブラシ摩耗限度検知装置。A side surface of the brush body is provided with a vertical groove having an opening at the lower end and a sloped surface directed downward from the side surface to the inside at the upper end, and an insulating member is installed on the outside of the wall of the brush holder into which the brush body is inserted. A notch is provided in the wall below the mounting part, and two conductive plate-like bodies are fixed to the mounting part with a predetermined interval and projecting upwardly and downwardly approximately parallel to the wall. Brush wear is achieved by forming a bent portion at the lower end of the plate-like body to reach the groove of the brush body, and further connecting an electric circuit between the conductive plate-like bodies with an indicator that displays the wear limit of the brush. Limit detection device.
