It is assembled by a plurality of parts, and an easy screw end method is mainstream, and the resolution after at the time of assembling and the assembling is used for an electric appliance and a car, an airplane, a train, the machine tool in that by the various joining method. However, because external force such as vibration and the repetition load acts on the join of the screw, the screw loses a conclusion power, and the slack occurs. This phenomenon causes a serious accident to give material and human damage. In contrast, it is dealt by the slack laboratory procedure of various screws, but lower unevenness and reliability of the measured value, the inspection that let you maintain proofreading and a conclusion state of the screw head again have a problem that it is difficult, and there is not the laboratory procedure that is simple and easy and highly precise in the present conditions. Therefore, in this study, I report it because I studied the slack of the screw which occurs because a spindle is lost by external force for the purpose of the detection of the slack and a thing judging more easily than the method and exactly in before.
