The box has a side plate that forms a side surface and a back plate that forms a back surface, and the back plate is provided with a bent portion with both side portions bent forward, and the bent portion at the rear end of the side plate. It is characterized by providing a holding portion for holding the elastic member, and the bent portion has a plurality of protrusions formed by plastic deformation.
　また本発明は、上記構成の冷蔵庫において、前記突起部が上下方向に延びて上下方向に並設されることを特徴とする。 Further, according to the present invention, in the refrigerator having the above-described configuration, the protrusions extend in the vertical direction and are arranged in parallel in the vertical direction.
　また本発明は、上記構成の冷蔵庫において、前記突起部が水平方向に複数列設けられ、隣接する列の前記突起部が上下方向にずれて配されることを特徴とする。 Further, the present invention is characterized in that in the refrigerator configured as described above, the protrusions are provided in a plurality of rows in the horizontal direction, and the protrusions in adjacent rows are shifted in the vertical direction.
　また本発明は、上記構成の冷蔵庫において、前記突起部が前後方向に延びて上下方向に並設されることを特徴とする。 Further, the present invention is characterized in that, in the refrigerator configured as described above, the protrusions extend in the front-rear direction and are arranged in parallel in the vertical direction.

The protrusions 51 extend in the vertical direction, and a plurality of the protrusions 51 are arranged in parallel up and down via the gap 53.
　また、突起部５１は隙間５４を介して水平方向に複数列設けられ、隣接する列の突起部５１が上下方向にずれて配される。なお、同図において突起部５１が２列設けられるが、３列以上設けてもよい。 Further, the protrusions 51 are provided in a plurality of rows in the horizontal direction via the gaps 54, and the protrusions 51 in the adjacent rows are shifted in the vertical direction. In the figure, two rows of protrusions 51 are provided, but three or more rows may be provided.
　図５は図２のＢ－Ｂ線で切断した上面断面図を示している。側面板４４は両側の後端４４ａを折り返してＵ字状に屈曲した保持部５２を有している。保持部５２は弾性により折曲部５０を保持している。この時、突起部５１の先端は保持部５２の側壁５２ｂに当接する。また、保持部５２には発泡断熱材２３が漏出しない程度の大きさ（例えば直径１ｍｍ）に形成されるガス抜孔５２ａが形成されている。 FIG. 5 shows a top cross-sectional view taken along the line BB in FIG. The side plate 44 has a holding portion 52 that is bent in a U shape by folding back the rear ends 44a on both sides. The holding part 52 holds the bent part 50 by elasticity. At this time, the tip of the protrusion 51 comes into contact with the side wall 52 b of the holding part 52. Further, the holding portion 52 is formed with a gas vent hole 52a formed to a size (for example, a diameter of 1 mm) to the extent that the foam heat insulating material 23 does not leak.
　上記構成の冷蔵庫１において、発泡断熱材２３の原液が注入口４５から充填されると、発泡により発生するガスは保持部５２のガス抜孔５２ａに進入する。そして、ガスは突起部５１間に形成される隙間５３、５４を通って冷蔵庫１の外側に排気される。 In the refrigerator 1 configured as described above, when the stock solution of the foam heat insulating material 23 is filled from the inlet 45, the gas generated by foaming enters the gas vent hole 52a of the holding portion 52. The gas is exhausted to the outside of the refrigerator 1 through gaps 53 and 54 formed between the protrusions 51.
　本実施形態によると、外箱８の背面板４０の両側部に設けた折曲部５０が塑性変形により形成される複数の突起部５１を有する。これにより、背面板４０が補強され、外箱９を薄肉化しても背面板４０の折れ曲がりを防止することができる。従って、冷蔵庫１のコストを削減するとともに歩留りを向上することができる。また、保持部５２内に配される折曲部５０の複数の突起部５１間を介して発泡断熱材２３の発泡時のガスが排気される。このため、冷蔵庫１の背面にガス抜孔を設ける必要がなく、冷蔵庫１の美観を向上することができる。 According to the present embodiment, the bent portions 50 provided on both sides of the back plate 40 of the outer box 8 have a plurality of protrusions 51 formed by plastic deformation. Thereby, even if the back plate 40 is reinforced and the outer box 9 is thinned, the back plate 40 can be prevented from being bent. Therefore, the cost of the refrigerator 1 can be reduced and the yield can be improved. Moreover, the gas at the time of foaming of the foam heat insulating material 23 is exhausted through the space between the plurality of protrusions 51 of the bent part 50 arranged in the holding part 52. For this reason, it is not necessary to provide a gas vent in the back surface of the refrigerator 1, and the aesthetics of the refrigerator 1 can be improved.
　また、突起部５１が上下方向に延びて隙間５３を介して上下方向に並設されるため、発泡断熱材２３が充填される際に発生するガスを容易に排気することができる。 Moreover, since the protrusions 51 extend in the vertical direction and are arranged in parallel in the vertical direction via the gap 53, the gas generated when the foam heat insulating material 23 is filled can be easily exhausted.
　また、突起部５１が水平方向に複数列設けられ、隣接する列の突起部５１が上下方向にずれて配されるため、背面板４０をより補強するとともに、隙間５３を介した保持部５２内への異物進入を防止することができる。 In addition, since the protrusions 51 are provided in a plurality of rows in the horizontal direction and the protrusions 51 in adjacent rows are shifted in the vertical direction, the back plate 40 is further reinforced, and the inside of the holding portion 52 through the gap 53 is also provided. It is possible to prevent foreign matter from entering.
　また、本実施形態において、折曲部５０の内面側と外面側とを連通させる貫通孔を設けてもよい。これにより、保持部５２に進入したガスが貫通孔を介して折曲部５０の外面側に導かれ、ガスを容易に排気することができる。 Further, in the present embodiment, a through hole that communicates the inner surface side and the outer surface side of the bent portion 50 may be provided. Thereby, the gas that has entered the holding portion 52 is guided to the outer surface side of the bent portion 50 through the through hole, and the gas can be easily discharged.

For convenience of explanation, the same parts as those in the first embodiment are denoted by the same reference numerals.
　背面板４０の折曲部５０には水平方向に延びる複数の突起部５１が配されている。突起部５１は背面板４０のプレス加工によって塑性変形して形成され、折曲部５０の上部から下部まで水平方向に延びて上下方向に隙間５５を有して並設されている。なお、突起部５１を水平方向に複数設けてもよい。 A plurality of protrusions 51 extending in the horizontal direction are arranged on the bent portion 50 of the back plate 40. The protrusion 51 is formed by plastic deformation by pressing the back plate 40, extends in the horizontal direction from the upper part to the lower part of the bent part 50, and is provided side by side with a gap 55 in the vertical direction. A plurality of protrusions 51 may be provided in the horizontal direction.
　本実施形態によると、第１実施形態と同様の効果を得ることができる。 According to this embodiment, the same effect as that of the first embodiment can be obtained.
　＜第３実施形態＞
　次に、第３実施形態の冷蔵庫１について説明する。本実施形態は第１実施形態の突起部５１の形状が異なっている。その他の部分は第１実施形態と同様である。図９は本実施形態の背面板４０の要部の斜視図を示し、図１０は図９のＥ－Ｅ線で切断した上面断面図を示している。説明の便宜上、第１実施形態と同様の部分には同一の符号を付している。 <Third Embodiment>
Next, the refrigerator 1 of 3rd Embodiment is demonstrated. In the present embodiment, the shape of the protrusion 51 of the first embodiment is different. Other parts are the same as those in the first embodiment. FIG. 9 is a perspective view of a main part of the back plate 40 of the present embodiment, and FIG. 10 is a top sectional view taken along line EE of FIG. For convenience of explanation, the same parts as those in the first embodiment are denoted by the same reference numerals.
　背面板４０の折曲部５０には水平方向に延びる複数の突起部５１が設けられる。突起部５１は背面板４０のプレス加工によって塑性変形して形成される。突起部５１は内側（対向する折曲部５０側）に向かって突出し、折曲部５０の前端まで延びて形成される。 The bent portion 50 of the back plate 40 is provided with a plurality of protrusions 51 extending in the horizontal direction. The protrusion 51 is formed by plastic deformation by pressing the back plate 40. The protrusion 51 protrudes toward the inner side (opposing bent part 50 side) and extends to the front end of the bent part 50.
　また、突起部５１の外面側に形成される溝部５６は前面５６ａを開放され、後端５６ｂは側面板４４の後端４４ａよりも後方に配される。これにより、発泡断熱材２３の発泡時に保持部５２内に進入したガスが溝部５６を介して排気される。 Further, the groove portion 56 formed on the outer surface side of the projection portion 51 has the front surface 56 a opened, and the rear end 56 b is arranged behind the rear end 44 a of the side plate 44. As a result, the gas that has entered the holding portion 52 when the foam heat insulating material 23 is foamed is exhausted through the groove portion 56.
　本実施形態によると、突起部５１が前後方向に延びて上下方向に並設されるため、第１実施形態と同様の効果を得ることができる。 According to the present embodiment, since the protrusions 51 extend in the front-rear direction and are arranged in parallel in the up-down direction, the same effect as in the first embodiment can be obtained.
　また、突起部５１の外面側に形成される溝部５６の前面５６ａが開放され、後端５６ｂが側面板４４の後端４４ａよりも後方に配される。このため、発泡断熱材２３の発泡時のガスは溝部５６を介して排気することができる。溝部５６は外側から見えない保持部５２内に配されているため、冷蔵庫１の美観の低下を防止することができる。 Further, the front surface 56a of the groove portion 56 formed on the outer surface side of the protruding portion 51 is opened, and the rear end 56b is arranged behind the rear end 44a of the side plate 44. For this reason, the gas at the time of foaming of the foam heat insulating material 23 can be exhausted through the groove part 56. Since the groove part 56 is arranged in the holding part 52 that cannot be seen from the outside, it is possible to prevent the appearance of the refrigerator 1 from being deteriorated.
