（８）内に取付ける。(10) is a steel plate reinforcing member. The reinforcing member (10) is formed by folding a flat plate at 180 ° C, and further by folding it at 180 ° to form engagement grooves (11) and (12).
The engaging groove (11) is inserted into the continuous groove (8), and the folded flange (7) is inserted into the engaging groove (12).
The end on the outer box (5) side is fixed to the inner surface of the outer box (5) with a tape (13). At this time, the outer surface of the engaging groove (11) is in close contact with the inner surface of the continuous groove (8) and engages with the continuous groove (8).
As shown in FIG. 2, the heat insulating box (2) is attached at two locations on the long side and one location on the short side, for a total of six locations. The engaging groove (11) has a cross-sectional shape in which the inner part (11b) is expanded more than the inlet (11a), and the high temperature refrigerant pipe (P) is the engaging groove (11) inlet of the reinforcing member (10). It is inserted into and engaged with the inner part (11b) from (11a) and is arranged and held in the continuous groove (8). Reference numeral (15) is a sealing material, which is installed in the engaging groove (11) and the continuous groove (8) in the portion where the reinforcing member (10) is not present.
