摘要：A tightening tool such as a torque wrench is provided in which electric powercan be fed to an electronic circuit with eliminating the need for a battery and achievingdaily maintenance-free. In the tightening tool, when a tightening torque has reached a settorque value and a torque limiter is actuated, an electronic circuit unit that has obtained adetection signal outputted from a torque limiter actuation detection unit outputs atightening completion signal. The tightening tool has a power generation unit for feedingelectric power to the electronic circuit unit at least during the actuation of the torquelimiter. The power generation unit performs photovoltaic power generation,electromagnetic induction power generation, power generation by conversion frommechanical energy into electrical energy, or temperature difference power generation.
