The screw 57 c that has passed through the hole 17 b 3 and the screw insertion hole 10 b of the front partition member 10 is screwed to the screw screw hole 56 c of the reinforcing member 56. Thus, a part of the hinge member 17 b provided on the left-side wall heat insulating panel 26 is fastened to the vertical reinforcing member 51. In this case, a part of the hinge member 17 b is fastened to the vertical reinforcing member 51 via the reinforcing contact member 56.

次に、前仕切部材１１と左側壁用断熱パネル２６との接合部分、前仕切部材１１と右側壁用断熱パネル２７との接合部分とについて説明するが、両部分は左右対称形であるので、前仕切部材１１と左側壁用断熱パネル２６との接合部分について、図１４及び図１５を参照して説明する。すなわち、縦補強部材５１は、当該前仕切部材１１との接合部においては、既述したように図１０に示した前記内側板部５１ｃが切除されたＬ状をなす。さらに外板３０Ｂの図１０に示した内側延出部３０ｂ３も切除されている。そして、縦補強部材５１と補強当て部材６１とにより前仕切部材１１が取り付けられている。 Next, the joint portion between the front partition member 11 and the left-side wall heat insulation panel 26 and the joint portion between the front partition member 11 and the right-side wall heat insulation panel 27 will be described. A joint portion between the front partition member 11 and the left side wall heat insulation panel 26 will be described with reference to FIGS. 14 and 15. That is, the vertical reinforcing member 51 has an L shape in which the inner plate portion 51c shown in FIG. 10 is cut off at the joint portion with the front partition member 11 as described above. Further, the inner extension 30b3 shown in FIG. 10 of the outer plate 30B is also cut away. The front partition member 11 is attached by the vertical reinforcing member 51 and the reinforcing contact member 61.

すなわち、外板３０Ｂの中間部３０ｂ２には、ねじ挿通孔部３０ｍが形成され、さらに、縦補強部材５１の中間板部５１ｂにもねじ挿通孔部５１ｂ２が形成されている。
さらに前記補強当て部材６１は前記補強当て板５６と同じ構成であり、３つのねじ螺合孔部６１ａ〜６１ｃが形成されていると共に、皿状の凹み部６１ｄが形成され、この凹み部６１ｄの底部にねじ挿通孔部６１ｅが形成されている。さらに前記前仕切部材１１にはねじ挿通孔部１１ａ、１１ｂが形成されている。 That is, a screw insertion hole 30m is formed in the intermediate portion 30b2 of the outer plate 30B, and a screw insertion hole 51b2 is also formed in the intermediate plate 51b of the vertical reinforcing member 51.
Further, the reinforcing abutting member 61 has the same configuration as the reinforcing abutting plate 56, is formed with three screw threading hole portions 61a to 61c, and is formed with a dish-like recessed portion 61d. A screw insertion hole 61e is formed at the bottom. Furthermore, the front partition member 11 is formed with screw insertion holes 11a and 11b.

そして、前記補強当て部材６１を縦補強部材５１及び前仕切部材１１の裏側に配置し、外板３０Ｂのねじ挿通孔部３０ｍ及び縦補強部材５１のねじ挿通孔部５１ｂ２を通したねじ６２ａを補強当て部材６１のねじ螺合孔部６１ａにねじ締めし、前仕切部材１１のねじ挿通孔部１１ａを通したねじ６２ｂを補強当て部材６１のねじ螺合孔部６１ｂにねじ締めし、そして、前仕切部材１１のねじ挿通孔部１１ｂを通したねじ６２ｃを補強当て部材６１のねじ螺合孔部６１ｃにねじ締めする。 Then, the reinforcing abutting member 61 is disposed on the back side of the vertical reinforcing member 51 and the front partition member 11, and the screw 62a that passes through the screw insertion hole 30m of the outer plate 30B and the screw insertion hole 51b2 of the vertical reinforcing member 51 is reinforced. The screw 62b through the screw insertion hole portion 11a of the front partition member 11 is screwed into the screw screw hole portion 61b of the reinforcing pad member 61, and the front screw member 61 is screwed into the screw screw hole portion 61a. The screw 62 c that has passed through the screw insertion hole portion 11 b of the partition member 11 is screwed into the screw screw hole portion 61 c of the reinforcing contact member 61.

なお、前仕切部材１１の裏側には、合成樹脂製の仕切裏カバー６３が設けられている。すなわち、この仕切裏カバー６３は、前仕切部材１１の取り付け前において、予め前記補強当て部材６１のねじ挿通孔部６１ｅに通したねじ（皿ねじ）６４により当該補強当て部材６１を介して前仕切部材１１に固定されている。さらに、前記仕切裏カバー６３は、左側壁用断熱パネル２６に設けられた支持具６５により支持されている。 A synthetic resin partition back cover 63 is provided on the back side of the front partition member 11. That is, the partition back cover 63 is connected to the front partitioning member 61 through the reinforcing contact member 61 by a screw (head screw) 64 that has been passed through the screw insertion hole 61e of the reinforcing contact member 61 in advance before the front partition member 11 is attached. It is fixed to the member 11. Further, the partition back cover 63 is supported by a support 65 provided on the left side wall heat insulation panel 26.

この支持具６５は、突出部６５ａと、この突出部６５ａから上下方向に延出する延出部６５ｂ、６５ｃとを有する。そして、この支持具６５は、左側壁用断熱パネル２６の組み立て前に、その突出部６５ａが内板３１Ｂの孔部３１ｋに裏側から挿入されて表側に突出され、延出部６５ｂ、６５ｃが内板３１Ｂ裏面に接着されている。左側壁用断熱パネル２６の組み立て完成状態では、この延出部６５ｂ、６５ｃは真空断熱パネル３２にも接着され、内板３１Ｂと真空断熱パネル３２とで挟持されている。 The support tool 65 includes a projecting portion 65a and extending portions 65b and 65c extending from the projecting portion 65a in the vertical direction. Before the left side wall heat insulation panel 26 is assembled, the support 65 is inserted into the hole 31k of the inner plate 31B from the back side and protrudes to the front side, and the extension portions 65b and 65c are provided inside. It is bonded to the back surface of the plate 31B. In the assembled state of the left side wall heat insulating panel 26, the extending portions 65b and 65c are also bonded to the vacuum heat insulating panel 32 and are sandwiched between the inner plate 31B and the vacuum heat insulating panel 32.

前記突出部６５ａには、ねじ挿通孔部６５ｄが形成されており、このねじ挿通孔部６５ｄは、左右方向に若干長い長孔状に形成されている。
一方、前記仕切裏カバー６３の下部には、固定具６５により支持される被支持部６３ａが凹んで形成されている。そして、この被支持部６３ａにはねじ螺合孔部６３ｂが形成されている。又、この仕切裏カバー６３は、左側壁用断熱パネル２６及び右側壁用断熱パネル２７との間には予め隙間Ｇが存するように、その左右長さ寸法が設定されている。つまり、左側壁用断熱パネル２６及び右側壁用断熱パネル２７は、製造時において、断熱キャビネット２は外側幅寸法Ｈｓ（図６参照）を順守するように組み立てられるものであり、そうすると、左側壁用断熱パネル２６及び右側壁用断熱パネル２７の厚み寸法にばらつきが発生すると、内側幅寸法Ｈｕにばらつきが発生する。このばらつきを予め見越しても隙間Ｇが出る長さに設定されている。ただし、この隙間Ｇは僅かであり、仮に左側壁用断熱パネル２６及び右側壁用断熱パネル２７が、冷却時において内外側部の熱収縮率の差によって湾曲しようとした場合でも、大きな湾曲を阻止できる程度に設定している。この隙間Ｇには、ソフトテープなどの断熱材を詰めても良い。 The protrusion 65a is formed with a screw insertion hole 65d, and the screw insertion hole 65d is formed in a long hole shape that is slightly longer in the left-right direction.
On the other hand, a supported portion 63a supported by a fixture 65 is formed in the lower portion of the partition back cover 63 so as to be recessed. A screw screw hole 63b is formed in the supported portion 63a. The left and right length dimensions of the partition back cover 63 are set so that a gap G exists in advance between the left side wall heat insulation panel 26 and the right side wall heat insulation panel 27. That is, the heat insulation panel 26 for the left side wall and the heat insulation panel 27 for the right side wall are assembled so that the heat insulation cabinet 2 complies with the outer width dimension Hs (see FIG. 6) at the time of manufacture. When variations occur in the thickness dimensions of the heat insulation panel 26 and the right-side wall heat insulation panel 27, the inner width dimension Hu varies. Even if this variation is anticipated in advance, the length is set such that the gap G appears. However, the gap G is small, and even if the left-side wall heat insulation panel 26 and the right-side wall heat insulation panel 27 are about to bend due to the difference in thermal contraction rate between the inner and outer sides during cooling, a large bend is prevented. It is set as much as possible. The gap G may be filled with a heat insulating material such as soft tape.

そして、前記仕切裏カバー６３は、その下部が前記支持具６５により支持されて、ねじ挿通孔部６５ｄに通したねじ６６をねじ螺合孔部６３ｂにねじ止めすることにより、当該支持具６５により支持固定されている。 The lower part of the partition back cover 63 is supported by the support tool 65, and the screw 66 passed through the screw insertion hole part 65d is screwed to the screw screw hole part 63b. The support is fixed.
