Abstract

La présente invention concerne un dispositif amortisseur dont la taille peut être réduite tout en assurant suffisamment la rigidité d'une tige. Ce dispositif amortisseur (10) comprend un cylindre (20) et une tige de piston (30), la tige de piston (30) ayant une tige (40) et un piston (60) ayant une partie d'étanchéité formée sur sa circonférence externe ; une chambre à air étant formée à l'intérieur du cylindre (20) ; la tige (40) présentant un trou traversant (50) passant à travers celle-ci dans une direction croisant la direction de mouvement du piston (60) ; et le piston (60) présentant un orifice (70) qui est disposé dans une plage chevauchant le trou traversant (50) lorsque la tige (40) est vue dans la direction axiale, et qui présente une extrémité communiquant avec le trou traversant (50) et l'autre extrémité communiquant avec la chambre à air.
