Abstract
The invention seek to enable to share main components other than a tightening unit even in use for different effective lengths corresponding to ranges of tightening torques. There are provided: a tightening unitsuch as a ratchet; a housinghaving a two-divided structure including a front side cover partand a back side grip part; a strain bodyprovided inside the housingand replaceably coupling the tightening unitthereto; a distortion sensor, provided to the strain body, for detecting the distorted amount of the strain bodydue to the tightening force of the tightening unit; a microprocessor chiphaving functions including computing the tightening torque of the tightening unitbased on torque reference values prepared in advance and detection results of the distortion sensor; and an output unitfor outputting such as the tightening torque.
