The heat insulating wall 25 is provided in a gap between a steel plate outer box 29 forming the outer surface of the storage box main body 24 and an inner box 30 forming the wall surface of the inner chamber 26 arranged with an appropriate gap therein. The heat insulating material 31 is formed by filling and foaming a foaming resin. The rear wall 32 of the interior chamber 26 is bent so that the upper part bulges rearward, and a vertical partition wall 33 is disposed in front of the rear wall 32 with an appropriate gap. A space in front of the partition wall 33 is a storage space 34 for wine bottles, and the support shelf 28 is provided.

A flange 35 is bent on the outer peripheral end surface of the partition wall 33. Reference numeral 36 denotes a groove formed on the outer peripheral portion of the inner surface of the inner box 30, and reference numeral 37 denotes a flat portion formed inside the groove 36 so as to be continuous with the groove 36. 38
Is a step portion, which is formed inside the plane portion 37 and is formed toward the back side, and forms a part of the back surface.

The flange 35 of the partition wall 33 is engaged with the groove 36 and screwed directly to the flat surface 37. Further, a cool air passage 39 is formed in a space between the rear wall 32 and the partition wall 33 surrounded by the stepped portion 38 and a cooler 40 and a cooling fan 41 are provided. The cooler 40 is supported by receiving its lower part by receiving seats 42 formed on both sides of the step part 38.
