Abstract

L'objet de la présente invention est de concevoir un mécanisme de direction pour dispositif d'arbre extérieur, le mécanisme de direction étant capable de modifier la position de montage d'un actionneur conformément aux structures agencées tout autour et à la forme d'une coque. Un mécanisme de direction (100) pour un dispositif d'arbre extérieur est muni d'un dispositif d'arbre extérieur (10), d'un actionneur (20) qui tourne autour du dispositif d'arbre extérieur (10) et d'une attache (30) qui soutient l'actionneur (20) ; l'attache (30) dispose de parties de bras (31) sur les deux côtés droit et gauche dans une position telle que le dispositif d'arbre extérieur (10) se trouve au milieu d'un gouvernail en tant que centre, et l'actionneur (20) peut être monté sur l'une ou l'autre partie de bras (31) de l'attache (30).
