LOOSENESS PREVENTION NUT AND REPAIR METHOD OF INSTALLATION STRUCTURE
To provide a looseness prevention nut which enables fastening work to be performed easily and securely regardless of an extra length of a bolt.SOLUTION: A looseness prevention nut 1 includes: a hollow cylindrical body 10 in which a female screw part is formed on an inner peripheral surface; and a spiral coil spring 20 in which the base end side is fixed to the inner peripheral surface of the body 10 and the tip side protrudes from the body 10. The looseness prevention nut 1 is configured so that a bolt, which is inserted from the spiral tip side of the coil spring 20, is threadedly engaged with both of the coil spring 20 and the female screw part.SELECTED DRAWING: Figure 1
【課題】 ボルトの余長に拘らず締結作業を容易且つ確実に行うことができる緩み止めナットを提供する。【解決手段】 内周面に雌ねじ部が形成された中空筒状の本体１０と、基端側が本体１０の内周面に固定され、先端側が本体１０から突出する螺旋状のコイルばね２０とを備え、コイルばね２０の螺旋状の先端側から挿入されたボルトが、コイルばね２０および雌ねじ部の双方に螺合するように構成された緩み止めナット１。【選択図】 図１
