Abstract

PURPOSE: To make a compact device having a durability and a fidelity by arranging hydraulic liquid passage in a supporting shaft of a hydraulic cylinder so as not to expose a flexible tube out of the ship.
CONSTITUTION: A connection part of the base 5b in the hydraulic cylinder device 5 is formed such that the supporting shaft 9 is rotatably supported in the supporting frame 2, the base portion 5b of the cylinder 5a is fitted in the supporting shaft 9 and then fixed by the setting screw 10. One end of the supporting shaft is projected into the ship, one end of the two hydraulic liquid passages 11, 12 is opened inside the ship and then connected to a source of hydraulic pressure. The ends of the passages 11 and 12 are opened at the outer circumference surface of the supporting shaft 9 at a position where by they are fitted to the base portion 5b, and then are communicated with a head chamber and a rod chamber of the cylinder 5a. Therefore, it is possible to eliminate a flexible tube which is exposed outside the ship.
