Abstract:
(EN) [Problem] To provide a nut that is easy to fasten and does not come loose. [Solution] This nut 600 comprises: a nut body 10 in which a screw hole 30 is formed; an annular member 41 formed on the top surface side of the nut body 10; and an outer frame member 45 formed on the outer edge side of the annular member 41. The annular member 41 includes a second end 42b contacting a top surface 11 of the nut body 10, and a first end 42a positioned on the side opposite the second end 42b. The top surface of the first end 42a is positioned above the top surface of the second end 42b. A first gap 40 is formed between the first end 42a and the top surface 11 of the nut body 10. A lateral face of the annular member 41 is disposed between inner walls 47 of the outer frame member 45 across a second gap 49. The top surface of the first end 42a of the annular member 41 is positioned above a top surface 46 of the outer frame member 45. The inner wall 47 of the outer frame member 45 is inclined in a tapered shape toward the upward direction. A lateral face of the 41 is disposed between 47 or the 45, with a second 49 therebetween.
(FR) Le problème décrit par la présente invention est de fournir un écrou qui est facile à fixer et ne se desserre pas. La solution selon la présente invention concerne un écrou 600 comprenant: un corps d'écrou 10 dans lequel est formé un trou de vis 30; un élément annulaire 41 formé sur le côté de surface supérieure du corps d'écrou 10; et un élément de cadre externe 45 formé sur le côté de bord externe de l'élément annulaire 41. L'élément annulaire 41 comprend une seconde extrémité 42b en contact avec une surface supérieure 11 du corps d'écrou 10, et une première extrémité 42a positionnée sur le côté opposé à la seconde extrémité 42b. La surface supérieure de la première extrémité 42a est positionnée au-dessus de la surface supérieure de la seconde extrémité 42b. Un premier espace 40 est formé entre la première extrémité 42a et la surface supérieure 11 du corps d'écrou 10. Une face latérale de l'élément annulaire 41 est disposée entre des parois internes 47 de l'élément de cadre externe 45 à travers un second espace 49. La surface supérieure de la première extrémité 42a de l'élément annulaire 41 est positionnée au-dessus d'une surface supérieure 46 de l'élément de cadre externe 45. La paroi interne 47 de l'élément de cadre externe 45 est inclinée selon une forme effilée vers le haut. Une face latérale de l'élément annulaire 41 est disposée entre les parois internes 47 ou l'élément de cadre externe 45, avec un second espace 49 entre eux.
(JA) 【課題】緩み防止とともに締めやすいナットを提供する。 【解決手段】本発明のナット600は、ネジ孔30が形成されたナット本体部10と、ナット本体部10の上面側に形成された環状部材41と、環状部材41の外縁側に形成された外枠部材45とから構成されている。環状部材41は、ナット本体部10の上面11に接触している第2端部42bと、第2端部42bとは反対側に位置する第1端部42aとを有している。第1端部42aの上面は、第2端部42bの上面よりも上方に位置している。第1端部42aとナット本体部10の上面11との間には、第1隙間40が形成されている。環状部材41の側面は、外枠部材45の内壁47と間に第2隙間49を介して配置されている。環状部材41の第1端部42aの上面は、外枠部材45の上面46よりも上方に位置している。外枠部材45の内壁47は、上向きに向かってテーパ状に傾斜している。
