PROBLEM TO BE SOLVED: To improve the handling workability and heat retaining performance of heating cabinets and facilitate the manufacture and assembly of them by modifying especially their storage box. SOLUTION: A storage box 3 placed within a heat insulating box 2 comprises a left side wall 4, a right side wall 5, a ceiling plate 6 and a bottom plate 7, which all are extruded shapes of aluminum and have far-infrared radiation property. The left and right side walls 4 and 5 have multiple stages of opposed grooves 8 and 9 in their internal surface, in which shelves 15 fit for drawing action, and consist of a plurality of vertically joined units 4a and 5a, which are assembled when a line of projection on one end face of each unit is fitted in a line or recession in the adjacent end face of the adjacent unit. The shelves 15 have far-infrared radiation property and a plurality of ribs 16 extending in the drawing direction, and can hinge on the substantial middle of them in the drawing direction.
