Abstract:
1. An electric tool comprising: a body housing; a motor with a cooling fan that is housed in the body housing, the motor having an output shaft that defines an axial direction; a tip tool; a rotational transmission mechanism disposed in the body housing to transmit a rotational force of the output shaft of the motor to the tip tool; an air inlet formed on a peripheral surface of the body housing to introduce a cooling air into the body housing for cooling the motor; an air outlet formed on the peripheral surface of the body housing to discharge the cooling air to an outside of the body housing; and a cover member disposed on an inner wall or an outer wall of the body housing to cover the air inlet and the air outlet, the cover member being slidable in the axial direction between a first position where the air inlet and the air outlet are both opened and a second position where the air inlet and the air outlet are both closed, wherein an elastic member is interposed between the cover member and a surface of the body housing.
