PROBLEM TO BE SOLVED: To provide a nut rotation amount inspection tool and the like capable of easily and reliably determining whether or not unevenness in an amount of nut rotation after final fastening at a plurality of bolt joint parts satisfy an acceptance criterion within a prescribed range.SOLUTION: An inspection tool 1 in which a body part 3 where a rotating plate 7 setting a reference line 13 and area 15 and a rotating plate 9 setting a reference line 17 and area 19 are attached to a pin 11 so that they are independently rotatable is integrated with a rail 5 is used. With respect to a plurality of bolt joint parts 35, the reference line 13 of the rotating plate 7 is matched to a marking 33a-2 of a nut 29-2 whose amount of rotation is the least. The body 3 is slid and moved along the rail 5 and the reference line 17 of the rotating plate 9 is matched to a marking 33a-4 of the nut 29-4 whose amount of rotation is the largest. Then, unevenness in an amount of nut rotation is determined on the basis of an angle made by the reference line 13 of the rotating plate 7 and the reference line 17 of the rotating plate 9. |
