電動工具。 The switch box has an outer frame made of a metal member for storing reduction parts, impact structural parts, etc., and has an electronic circuit part built into the switch box that adjusts the rotational speed according to the amount of pull of the trigger, and a switching element for power adjustment such as an FET is connected to the switch box. In a battery-operated power tool with a rotational speed regulator, which includes a speed change switch fixed to a fin outside the box, and a handle that houses the speed change switch and battery and supports the main body, the fin is connected to a motor and an outer frame of a metal member. At the same time, an elastic body such as a rubber member is disposed between the motor and the fins, and the fins are configured to abut against the outer frame of the metal member, and the heat generated from the switching element such as the FET is disposed between the motor and the fins. A battery-powered power tool with a rotational speed regulator configured such that rotational speed is transmitted to the outer frame of the metal member via the fins.
