  • the foam insulating material 71 is formed thick since there is not a vacuum insulating material 59 at a portion of the U-shaped groove portion 61 which is constituted to project long toward the interior of the vegetable chamber 9. More specifically, the thickness of the foam insulating material 71 compensates heat-insulation performance lowered due to presence of a portion of the U-shaped groove portion 61 and heat-insulation performance of the foam insulating material 71 which is lower than that of the vacuum insulating material 59.
  • the projecting foam insulating material 71 in the projected upper throat portion 69 is formed to be thicker than the vacuum insulating material 59 below.
