    • An electric tool includes a housing; a motor that is housed in the housing; and a tip tool. A rotation transmission mechanism transmits a rotation of the motor to the tip tool. An air inlet is disposed on the housing to introduce a cooling air for cooling the motor from an outside of the housing and an air outlet is disposed to discharge the cooling air. A cover is slidable along an inner wall or an outer wall of the housing and is movable in a first position where the air inlet and the air outlet are opened and a second position where the air inlet and the air outlet are closed.
