The inner part of the third discharge duct 21 is placed on the receiving part 20a provided on the second discharge duct 20, and the front face is provided with a locking plate 22a provided on the partition part 22.
Into the groove 21a provided in the third discharge duct 21. Next, after the second partition wall 8 is attached from above, the urethane foam material is filled between the outer case 2 and the inner case 3 to become the heat insulating material 4. Therefore, after the urethane foaming, the low temperature chamber upper case 19 is connected to the third discharge duct. Even if it is inserted into the rail 21b formed integrally with the 21, it does not hit the third discharge duct 21.

Since the third discharge duct is integrally provided with a groove for stopping and a rail for receiving the upper case of the low-temperature chamber, there is no problem that the upper case of the low-temperature chamber is hit by deformation and deflection due to urethane foaming pressure. The dimensional relationship with the upper case in the low-temperature room is maintained, and the performance is stable. In addition, excellent effects can be obtained, such as simplification of the assembling work, no connecting member, and low cost.
