PURPOSE:To prevent the damage of the upper end of a hatch combing in loading and unloading, and to prevent the deterioration of refrigerating function, by furnishing entry guides close to the top of the hatch combing projecting upwards from the top, and connecting the entry guides by a connecting body. CONSTITUTION:Close to the top 1a of a hatch combing 1 with a wooden frame 4 at the top and a thermal insulating layer 5 at the lower part, entry guides 3 are furnished projecting upwards from the top 1a, and they are connected by a connecting body 13. Therefore, containers never contact the hatch combing 1 in the loading and unloading, and never hurt the wooden frame 4 installed at the top. Furthermore, since there is no need to furnish a steel plate to the wooden frame 4 as a protector, the input heat capacity is little, and the deterioration of the refrigerating function is prevented. Moreover, since the entry guides 3 are connected each other in a rectangular form by the connecting body 13 making a rigid structure, containers can be entered smoothly.
