Claims

[Scope of utility model registration request]

At the side rollers R4 and R3 of the branching part 3 of the panel P and the grating G or the bent part, and the bogie B part, the joists 2 and the grating G4
, G3 are extended and cantilevered at the ends of each panel P4, P3, and the ends of gratings G4, G3 and joist 2 are cut out so that the tops thereof form an acute angle, so that the gratings can touch each other during opening and closing operations. G4 and G3 are designed so that they do not interfere, and the joists 2 and gratings G3 and G2 are extended to above the bogie B at the side portions of panels P3 and P2, and cantilevers are supported at the ends of each panel P3 and P2. The hatch cover in the hold of a reefer ship is characterized in that the ends of the gratings G3, G2 and the joists 2 are cut out so that the upper parts thereof form an acute angle, so that the gratings G3, G2 do not interfere with each other during opening/closing operations.
