The fixing box 46 is disposed adjacent to the front end of the supporting frame 42, and in order to prevent the tow chain 45 from being exposed to the outside when the drawer type door body 20 is pulled open, the side plate 4253 of the mounting portion 425 extends rearward beyond the mounting space to the rear end of the supporting frame 42. Meanwhile, the supporting frame 42 is further protruded toward the interior of the compartment 11 to form a supporting protrusion 427, and the supporting protrusion 427 is preferably disposed at a middle position in the front-rear direction of the supporting frame 42, and the rear end of the fixed box 46 is spaced from the supporting protrusion 427. The intermediate position is not limited to the midpoint position of the support frame 42 in a strict sense, and may be a position near the midpoint of the support frame 42 in the front-rear direction. When the drawer-type door body 20 is pulled out, the supporting protrusion 427 can prevent a part of the chain link 451 of the drag chain 45 from falling down and exceeding the supporting frame 42, which affects the appearance; when the drawer door 20 is retracted to the closed state, the supporting protrusions 427 do not affect the folding and deformation of the towing chain 45. The side plate 4253 extends rearward beyond the support protrusions 427, and the support protrusions 427 are formed by folding and extending the lower edge of the side plate 4253 toward the compartment inner side. The support protrusions 427 are preferably arranged in a plate-like structure for supporting and limiting the drag chain 45.
