Abstract:
A power tool includes a brushless motor, a switching element, a power cable a rectifying device, a heat releasing member. The switching element controls a drive of the brushless motor. The power cable supplies an electric current to the brushless motor from power source. The rectifying device rectifies the electric current from the power cable. The heat releasing member is connected to the switching element and the rectifying device in order to enhance a cooling efficiency for the same.
