PROBLEM TO BE SOLVED: To provide an oil pulse tool formed compact in the longitudinal direction by improving the installation of the rotating position detection sensors and a torque detection sensor. SOLUTION: This oil pulse tool 1 includes a motor 3, an oil pulse unit 4 driven by the motor 3, and an output shaft 5 which is connected to the main shaft 24 of the oil pulse unit 4 and to which an end tool is attached. The oil pulse tool includes the rotating position detection sensors 13a, 13b for detecting the rotating position of the output shaft 5 and the torque detection sensor 12 for detecting the occurrence of an impact torque. The rotating position detection sensors and the torque detection sensor are installed on the output shaft 5 at the generally same position in the axial direction. The torque detection sensor is installed on the inner peripheral side, and the rotating position detection sensors are installed on the outer peripheral side. COPYRIGHT: (C)2010,JPO&INPIT
