Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ventilation device for a marine vessel of which an open state can be easily fixed.SOLUTION: An opening/closing handle bar 170 is rotatably fastened to a hatch hinge which rotatably combines a hatch cover 110 to a hatch frame 120, a guide projection 140 which is rotated forward in linkage with an opening operation of the hatch cover 110 and is rotated rearward in linkage with a shielding operation of the hatch cover 110, and a coupling shaft 123, and is provided with a long hole-shaped guide hole 151 along a lateral face thereof. The guide hole 151 has such a curvature as to be interlocked with rotational operation of the guide projection 140, and is so formed as to be restricted to an intermediate upper side in a vertical direction. An upper part of the guide hole 151 further extends rearward so as to form a support jaw, and thus, the guide hole is coupled to the guide projection 140 thereby guiding opening/closing operation of the hatch cover 110 and fixing an open state of the hatch cover 110 at a constant angle.SELECTED DRAWING: Figure 4
