Claims

[Scope of utility model registration request]

A drive shaft is provided parallel to the spindle that is rotated by an impact generator driven by an air motor, and a gear fixed to the rear end of this drive shaft and a gear fixed to the tip of the spindle are connected directly or indirectly. At the same time, the gear at the rear end of the drive shaft or the gear case supporting the drive shaft is connected to the air motor,
It is fixed to the main body case that houses the shock generating part and the spindle, and a strain sensor is installed on the outer periphery of the main body case, and the tightening torque is detected by twisting the main body case using the reaction force applied to the gear case that supports the drive shaft. A pneumatic tool with a strain sensor.
