PROBLEM TO BE SOLVED: To enable a large amount of air to be increased while passing through a condenser part in an aeration duct without increasing in particular a rotating speed of a cooling fan in a machine chamber and a thermal radiating amount of the condenser to be assured. SOLUTION: A caster 39 positioned at a suction side of a cooling fan 30 in at least a machine chamber 27, selected from casters 39 fixed to a bottom plate 31 of a machine chamber 27, is positioned and fixed outside the bottom plate 31 under a state in which it is covered from above by the bottom plate 31. Since it is possible to prevent air outside the machine chamber 27 from being sucked into the machine chamber 27 through the part of the caster 39 when the cooling fan 30 is being operated, it is possible to prevent an amount of air sucked into an aeration duct 34 through a suction port 36, thereby the amount of air passing through a condenser 38 within the aeration duct 34 can be increased without increasing a rotating speed of the cooling fan 34 in particular.
