<P>PROBLEM TO BE SOLVED: To avoid the breakage of legs of a coil and an electronic element which are connected to an inverter circuit board by improving the rigidity of the inverter circuit board to which switching elements are mounted. <P>SOLUTION: The power tool includes a motor, the inverter circuit board 4 fixed to the motor, a housing which houses the motor and the inverter circuit board, and a tip tool driven by the motor. The surface of the inverter circuit board 4 is reinforced by a reinforced member (shaded portion: an adhesive 16). The reinforced member is adhered in such a way to nearly cover one surface of the inverter circuit board 4 and, for example, an epoxy resin based adhesive. <P>COPYRIGHT: (C)2012,JPO&INPIT |
