Abstract
PURPOSE: To prevent opening and closing means for left and right hull parts from being immersed in the sea and unnecessitate a special division for the means by placing the means above the rotating sections of the left and right hull parts.
CONSTITUTION: A plurality of levers 3, 3' are erected on upper deck 1b, 1b' of the left and right hull parts 1a, 1a'. The roughly middle parts of the levers 3, 3' are connected by a connecting member 4 through a rotatable pin, while the upper ends of the levers are connected by a hydraulic cylinder 1. The opening and closing operations of the left and right hull parts 1a, 1a' and conducted by the stretching and retracting operations of the cylinder 1. Since the hydraulic cylinder 1 serving as the opening and closing means for the hulls 1a, 1a' is placed at an upper position, the cylinder 1 is prevented from being immersed in the sea.
