摘要： The problem to be overcome by the present disclosure is to provide an electric tool that may reduce the chances of fastening a fastening member excessively. An electric tool (1) according to the present disclosure includes a motor (2), a holding member (3), a transmission mechanism (4), a torque detection unit (5), a control unit (6), and a clutch mechanism (7). The holding member (3) holds a tip tool thereon. The transmission mechanism (4) transmits torque of the motor (2) to the holding member (3). The torque detection unit (5) detects the torque transmitted from the motor (2) to the holding member (3). The control unit (6) stops running the motor (2) when the torque detected by the torque detection unit (5) reaches first preset torque (T 1). The clutch mechanism (7) switches, when the torque transmitted from the motor (2) to the holding member (3) reaches second preset torque (T2), from a transmitting state where the torque of the motor (2) is transmitted to the holding member (3) to a cutoff state where transmission of the torque of the motor (2) to the holding member (3) is cut off.
