Abstract

L'invention porte sur un dispositif de câble, lequel dispositif a un mécanisme d'absorption de surcharge hautement élastique. Ce dispositif de câble comprend : un corps rotatif sur lequel un câble côté manipulation est enroulé et relié ; un corps suivant qui est relié au corps rotatif ; et un mécanisme d'absorption de surcharge, qui est disposé entre le corps rotatif et le corps suivant, qui vient en prise avec le corps rotatif et le corps suivant et qui tourne à l'unisson avec ceux-ci avant qu'une quantité de manipulation du câble côté manipulation n'atteigne une quantité prescrite, et, après que la quantité de manipulation du câble côté manipulation a atteint la quantité prescrite, le corps rotatif se déplaçant par rapport au corps suivant approximativement dans la même direction que celle dans laquelle une force est appliquée au corps rotatif par le câble côté manipulation.
