Claims

[Scope of utility model registration request]

(1) The driving force of the air motor is transmitted to the drive shaft via a planetary gear type reduction mechanism and a hydraulic pulse generator, and a reaction force detection arm provided on the internal gear of the planetary gear type reduction mechanism. The pilot chamber of the control valve that locks the snag detection valve and controls the supply of air to the air motor communicates with the snag detection valve through a passage having a throttle valve and a timer chamber sequentially from the snag detection valve side. When the tightening torque becomes a snag torque, the reaction force detection arm provided on the above gear is displaced to release the lock between the reaction force detection arm and the snag detection bar lubricant. A hydraulic type characterized in that the detection valve is opened, air is supplied to the timer chamber through the snag detection valve and the throttle valve, and the control valve is closed after a predetermined time depending on the opening degree of the throttle valve. (2) The hydraulic non-moving tool according to claim 1, wherein the planetary gear reduction mechanism is disposed between the air motor and the hydraulic pulse generator.
