Patent attributes
An electric power tool includes a housing, a commutator motor housed in the housing, and a brush holder disposed in the housing. A fan is disposed to the commutator motor. The brush holder includes a metal sleeve and a resin base. The metal sleeve houses a brush, and the resin base holds the metal sleeve at one surface side of the resin base. The resin base includes an opening portion exposing the metal sleeve to the opposite side surface of the one surface side. The brush holder is disposed in a direction that the resin base is disposed at the fan side such that rotation of the fan causes air suctioned from an air intake opening disposed in the housing at the metal sleeve side to be discharged from an exhaust outlet disposed in the housing at the fan side after passing through the brush holder and a commutator.
