  • the terminal support mechanism 10 described above has the vibration suppression mechanism 1 that can suppress the vibration of the rod member 3, thereby suppressing the vibration from being transmitted to other components via the terminal support mechanism 10. Can do. Therefore, it is possible to prevent the generation of abnormal noise.

Abstract

L'invention concerne un mécanisme de suppression de vibrations (1), lequel mécanisme comporte : un élément cylindrique (2); un élément de tige (3) qui coulisse dans l'espace interne (20) de l'élément cylindrique (2); et un câble (4) qui a une extrémité reliée à l'élément de tige. L'élément de tige (3) comprend une partie de diamètre fixe (31) et une partie de diamètre réduit (32) adjacente à la partie de diamètre fixe (31). La partie de diamètre réduit (32) a une section de grand diamètre (32a) ayant un diamètre sensiblement identique au diamètre externe de la partie de diamètre fixe (31), et une section de petit diamètre (32b) ayant un diamètre inférieur au diamètre externe de la partie de diamètre fixe (31). L'élément cylindrique (2) comporte un premier élément élastique (51) et un second élément élastique (52) qui ont chacun un diamètre interne apte à coulisser sur la partie de diamètre fixe (31) et la section de grand diamètre (32a), et supportant chacun l'élément de tige (3) à partir de la périphérie externe. Selon cette configuration, les performances de coulissement de l'élément de tige (3) entre la partie de diamètre fixe (31) et la partie de diamètre réduit (32) ne sont pas inhibées, et la vibration peut être éliminée par l'un quelconque d'une pluralité des éléments élastiques.
