To provide a refrigerator wherein, when a plurality of condensers are mounted on the back surface of an inner box, a welding work for a coupling piper for coupling the condensers is facilitated, a displacement between the condensers is simply prevented, and further the need of a sealing member is eliminated to result in advantageous in the cost.

Step sections 3a, 3b are provided on the back surface of an inner box 3 located below a first condenser 15 and a second condenser 20, in which step sections 3a, 3b insertion holes 3a1, 3b1 are provided for inserting the first condenser 15 and the second condenser 20 from the back surface side of the inner box 3 into a refrigerator. Heat transfer pipes of the first condenser 15 and the second condenser 20 are connected with each other through a coupling pipe, and the first condenser 15 and the second condenser 20 are inserted through the insertion holes 3a1, 3b1 and disposed between a partition and the inner box 3. Thereafter, first drain toy 17 and a second drain toy 22 are inserted from the insertion holes 3a1, 3b1 and are mounted on the back surface of the inner box 3. Simultaneously, the insertion holes 3a1, 3b1 are sealed with first, second drain toys 17, 22, and the first condenser 15 and the second condenser 20 are fixed to the back surface of the inner box 3 with support means.
