An impact rotation tool includes a drive source (15) that generates power. An impact force generation unit (17) generates impact force by changing the power generated by the drive source (15) to pulsed torque. A shaft (21) transmits the pulsed torque to the distal tool with the generated impact force. A torque detector (26) generates a signal corresponding to the torque applied to the shaft (21). A determination unit (66) determines whether or not a torque value obtained from a signal corresponding to the torque has reached a predetermined torque value. A control unit (30) controls the drive source (15) to a predetermined driving state when the determination unit (66) determines that the torque value has reached the predetermined torque value. The determination unit (66) is arranged on the shaft (21). |
