PROBLEM TO BE SOLVED: To reduce the dimensions of a machine room without reducing the capacity for storing articles by reducing the number of parts for composing a cooling device being arranged in the machine room. SOLUTION: A condensation tube 54a of a condenser 54 for composing a cooling device 50 is buried in a heat insulator 16 while the condensation tube 54a is brought into contact with the inner surface of an outer box 12 for forming the outer shape of showcase 11 for cooling. Also, the condensation tube 54a is meanderingly arranged over nearly the entire surface so that a rear-surface part 12b and an upper-surface part 12c of the outer box 12 are effectively utilized. In this manner, the condensation tube 54a is brought into contact with the inner surface of the outer box 12, thus utilizing the outer box 12 as a heat sink, and efficiently performing heat radiation from a refrigerant in a high pressure state.
