Patent attributes
A power tool includes a body housing including a first grip, inlet facing a front surface of the first grip, first outlet, and second outlet; a brushless motor held on the body housing and including a rotational shaft; an output unit supported on the body housing in a reciprocable manner; a power transmission mechanism between the brushless motor and the output unit in the body housing to transmit rotational motion of the rotational shaft to the output unit; a controller held on the body housing to control the brushless motor; and a fan held on the body housing and mounted on the rotational shaft. The body housing allows air drawn through the inlet and having cooled the brushless motor to be divided into first and second outlet blows respectively cooling the power transmission mechanism and discharged through the first outlet, and cooling the controller and discharged through the second outlet.
