Title
(EN) BOLT NUT
(FR) ÉCROU DE BOULON
(JA) ボルトナット
Abstract
(EN)
A bolt nut (1) comprises a nut (2) including a substantially cylindrical nut main body (4), a plurality of nut divided bodies (4a), a substantially cylindrical cover body (5) that covers the nut main body (4), a cover-side tapered part formed on the inner wall of the cover body (5), a nut-side tapered part (4a) formed such that the outer diameter of the outer wall thereof decreases toward one end part of the nut main body (4) so as to correspond to the cover-side tapered part, a spring (6) accommodated together with the nut main body (4) in the cover body (5), and a lid body (7) covering the other end part of the cover body (5), the bolt nut having an irregular pitch such that a bolt thread, which is the thread ridge of the bolt, and a nut thread, which is the thread ridge of the nut main body (4), have different pitches.
(FR)
L'invention concerne un écrou de boulon (1) comprenant un écrou (2) incluant un corps principal d'écrou (4) sensiblement cylindrique, une pluralité de corps divisés d'écrou (4a), un corps de cache sensiblement cylindrique (5) qui recouvre le corps principal d'écrou (4), une partie effilée côté cache formée sur la paroi interne du corps de cache (5), une partie effilée côté écrou (4a) formée de telle sorte que le diamètre extérieur de la paroi externe de celle-ci diminue vers une partie d'extrémité du corps principal d'écrou (4) afin de correspondre à la partie effilée côté cache, un ressort (6) accueilli conjointement avec le corps principal d'écrou (4) dans le corps de cache (5), et un corps de couvercle (7) qui recouvre l'autre partie d'extrémité du corps de cache (5). L'écrou de boulon possède un pas irrégulier, de sorte qu'un filetage de boulon, qui est l'arête de filetage du boulon, et un filetage d'écrou, qui est l'arête de filetage du corps principal d'écrou (4), ont des pas différents.
