Therefore, the airtightness between the lid 32A and the case body 31 can be further improved. Further, according to the above configuration, as the case body 31 is moved forward, the gap formed between the rib 37 and the flange portion 36 can be increased. Therefore, the resistance when pulling out the case body 31 toward you can be reduced.

(Summary of the first embodiment)
As described above, the refrigerator 1 according to the present embodiment includes a heat insulating box body 50 having an inner box 70, an outer box 60, and a heat insulating material provided between the inner box 70 and the outer box 60. There is. In the refrigerating chamber 11 formed by the inner box 70 of the heat insulating box body 50, at least one vegetable case 30 configured to be movable in the front-rear direction in the refrigerating chamber 11 is provided. The vegetable case 30 includes a case main body 31, a lid portion 32, and a support member 33. The lid portion 32 covers the case main body 31 and forms a closed space in the vegetable case 30. The support member 33 supports the lid portion 32 on the inner box 70. The support member 33 is provided with a rail 34 for moving the case body 31 in the front-rear direction.

Like the refrigerator disclosed in Patent Document 1, in a configuration in which rails on both left and right sides for sliding the storage case in the front-rear direction are provided on the side surface of the inner box of the heat insulating box, the inside of the heat insulating box is provided. The dimensions between the rails on both the left and right sides are likely to fluctuate depending on the degree of expansion of the foam insulation material filled in. Therefore, the dimensions of the storage case arranged between the left and right rails are designed to be smaller in anticipation of the dimensional variation between the left and right rails.

Therefore, the dimensions between the rails on both the left and right sides may not fit well with the outer dimensions of the storage case. If the dimensions between the rails on both the left and right sides do not match the outer dimensions of the storage case well, an unnecessarily large gap will be created between the storage case and the rails, and the airtightness of the storage case tends to deteriorate. Become.

Further, in the configuration in which the protrusion on which the shelf board functioning as the lid of the storage case is placed is provided on the side surface of the inner box of the heat insulating box, the dimensions of the rail and the protrusion are likely to fluctuate. Therefore, in anticipation of dimensional fluctuations between the rail and the protrusions, the spacing is often large. Therefore, the gap between the shelf board provided above the storage case and the storage case becomes large, and the airtightness of the storage case tends to decrease.

In the present embodiment, the rail 34 is provided on the support member 33 (more specifically, the left side portion 33a and the right side portion 33b) attached to the inner box 70. Since the support member 33 is attached to a protrusion or the like formed on the inner box 70, it is not easily affected by the expansion of the inner wall of the inner box 70 when the foamed heat insulating material is filled. Therefore, the dimensions between the left and right rails 34 provided on the support member 33 are unlikely to fluctuate. Therefore, according to the configuration according to the present embodiment, it is possible to make it easier to match the dimensions between the rails on the left and right sides with the outer dimensions of the storage case.

Further, the lid portion 32 and the support member 33 are integrated members 32A. Therefore, the space from the flange portion 36 provided on the support member 33 to the upper lid portion 32 can be used as a closed space. Further, since the flange portion 36 and the rail 34 are integrally formed, the dimensional variation between the flange portion 36 and the rail 34 is less likely to occur, and the gap between the rib 37 and the flange portion 36 is minimized. be able to. As a result, the airtightness of the case body 31 can be improved.

When the storage case provided in the refrigerator 1 is used as a vegetable case for storing vegetables, there is a desire to prevent the inside of the case from drying out. In the present embodiment, by making the inside of the vegetable case 30 a closed space, it is possible to form an environment (that is, a state of temperature and humidity) different from other spaces in the refrigerating room 11. This facilitates the formation of an environment suitable for storing vegetables.

In the refrigerator 1 according to the present embodiment, the dimensions between the rails 34 on both the left and right sides and the outer dimensions of the vegetable case 30 (specifically, the case body 31) are more compatible with each other, so that the inside of the vegetable case 30 is sealed. It is possible to improve the sex. Therefore, a vegetable case 30 that is more suitable for storing vegetables can be obtained.

In the refrigerator 1 according to the present embodiment, two openings 33a and 33b are provided at the front end of the lid portion 32. Further, the openings 33a and 33b are provided with opening amount adjusting holes 34a and 34b, respectively.
