PROBLEM TO BE SOLVED: To adequately air-cool an electrically equipped box without making dimensions of a machine chamber greater. SOLUTION: An ice storing tank 12 is arranged inside a main body 38. The machine chamber 14, in which a freezing mechanism 22 is to be arranged, is defined below the tank 12; and a storage chamber 54, in which the electrically equipped box 58 is to be arranged, is defined in an upper part of the tank 12. A piping space 46 for making the machine chamber 14 communicate with the storage chamber 54 is defined on the backside of the tank 12. A part of external air, which is sucked into the machine chamber 14 by operating a cooling fan 18 of the freezing mechanism 22, is guided into the box 58 via the piping space 46, so that the box 58 can be cooled.
