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
【課題】開放状態を簡単に固定することができる船舶用換気装置を提供する。【解決手段】開閉ハンドルバー170はハッチカバー110をハッチ枠120に対して回動可能に結合させるハッチヒンジとハッチカバー110の開放動作に連動して前方に回動し、ハッチカバー110の遮蔽動作に連動して後方に回動するガイド突起140と締結軸123に回動可能に締結され、側面に沿って長孔形のガイドホール151が設けられる。該ガイドホール151は、ガイド突起140の回動動作に連動するように曲率を有し、上下方向に中間上側に限定されるように形成され、該ガイドホール151の上部が後方にさらに延びて支持顎を形成することにより、前記ガイド突起140と締結されてハッチカバー110の開閉動作をガイドし、ハッチカバー110の一定角度の開放状態を固定する。【選択図】図4
