PROBLEM TO BE SOLVED: To provide a rudder/propeller pulling-up device capable of simultaneously pulling up a rudder and a propeller by using a hydraulic force when sailing in the shallow or rock part of a sea or lake or a place where a water depth greatly changes, performing steering in any position of the vertical moving range of the rudder and the propeller, reducing time and labor and quickly coping with situations. SOLUTION: A steering shaft 2 having an attached rubber plate 1 and a propeller pulling-up stick 5 for pulling a propeller 3 are provided in a ship body so as to be freely moved vertically, the upper parts of the steering shaft 2 and the propeller pulling-up stick 5 are connected to each other by a connecting member 6, the steering shaft 2 rotatably connected to the connecting member 6, a pulling-up hydraulic cylinder 9 is provided for vertically moving the connecting member 6, and a rudder and the propeller are simultaneously pulled up by the pulling-up hydraulic cylinder 9. Also, a key, a cylindrical pipe 20 and a steering hydraulic cylinder 10 are connected by an arm 21, the steering shaft 2 being fitted around the cylindrical pipe 20 by a keyway. Thus, in any position of the vertical moving range of the steering shaft 2, the steering hydraulic cylinder 10 is operated to perform steering. |
