PROBLEM TO BE SOLVED: To surely seal cold air within a cooling chamber by closely contacting a door to an outer case, while increasing effective capacity of a storage by avoiding fore-and-aft thickness of the door from increasing, in a cold reserving chamber for a kitchen provided with a footstep riser part at a lower end of the door. SOLUTION: Joint surfaces S1 and S2 of the door 9 and the outer case 3 for receiving the door 9 are formed into flat surfaces inclined in outward tilting states from the footstep riser part 11 side toward an upper end of the door 9. A packing 12 to seal cold air is arranged in the joint surface S1 on the door 9 side. When the joint surfaces S1 and S2 are obliquely inclined, the joint surfaces S1 and S2 of the door 9 and the outer case 3 are surely and closely contacted by forming the surfaces S1 and S2 into the flat surfaces, although a step-like footstep riser part 11 is provided on the door 9. The fore-and-aft thickness of the door 9 can be avoided from increasing. COPYRIGHT: (C)2003,JPO
