Abstract: At a first timing when a tightening machine temporarily tightens a bolt, a distance sensor acquires a first distance image. A distance sensor controller measures a first recess amount of the head of the bolt at the first timing by the first distance image. A manipulator controller is configured to change a relative posture of an image sensor relative to the head of the bolt in accordance with a rotation angle by which the bolt is rotated from the first timing to a second timing. The distance sensor acquires a second distance image at the second timing, and the distance sensor controller measures a second recess amount of the head of the bolt at the second timing by the second distance image, so as to measure an axial tension of the bolt by use of a difference between the first recess amount and the second recess amount.
