PURPOSE:To open and close a lid to cover a hatch opening for sure simply by furnishing a guide rail with a stopper part on the edge of the hatch opening and providing the lid with a stay capable to catch the stopper at the top. CONSTITUTION:A hatch opening edge 12 is constructed by forming a risen part on a concave part 11 provided on a deck 10. A lid 13 is fixed on the edge of the said concave part 11 via a hinge member 14 to be opened and closed easily to cover the opening edge 12 inside. On one inner side of a circumferential flange 13a of the lid 13, a stay 15 is provided to be rotatable via a bracket 16 with a catching gain 17 and a stopping projection 18 on the lower edge of its top. Meanwhile, on one side of the opening edge 12, a guide rail 19 is furnished to guide the top of the stay 15 to be easily slid with a pin 21 to be caught by the gain 17 in its one end. This construction permits to open and close the lid 13 for sure simply via the catching between the gain 17 of the stay 15 and the pin 21. |
