  • Figure 11 is a cross-sectional perspective view showing the shape of the body in the process of manufacturing the anti-loosening nut according to an embodiment of the present invention.
  • the anti-loosening nut 1 has a through hole 1a for bolt insertion in the center thereof.
  • the anti-loosening nut 1 includes a body 20 constituting a main body and a spring 10 embedded in the body 20. The body 20 and the spring 10 are fastened to the bolt by forming a component in an assembled state.
  • a stopper 24 is formed below the spring room 22.
  • the stopper 24 is formed to protrude from the inner wall surface of the lower jaw portion 22a and the side wall portion 22b surrounding the spring room 22.
  • the stopper 24 is preferably spaced apart from the lower end of the spring 10 by a predetermined distance L 2 in the circumferential direction (see FIG. 6).
  • the separation distance L 2 is preferably secured long enough so that the anchor 11 is separated from the notch 23 and the spring 10 can start to rotate in the release direction. Therefore, it is preferable that the separation distance L 2 is larger than the length L 1 of the anchor 11 (see FIG. 5).

Abstract

L'invention concerne un écrou anti-desserrage incorporant un ressort conçu pour modifier la force de serrage selon une direction de serrage d'un boulon. L'écrou anti-desserrage comprend : une butée, présente à l'intérieur d'un logement du ressort, qui coince et retient une extrémité inférieure du ressort lorsqu'un boulon est desserré par une force de rotation d'une intensité de seuil ou plus prédéterminée; et un support formé sur le côté opposé de la butée pour retenir la base du ressort.
