Claim:
A cold storage including a thermal insulating housing, a storage room constructed in the thermal insulating housing, and a machine room constructed under the storage room, comprising: a cooling unit integrated with a cooler and a blower accommodated in a cooling chamber constructed in a cooling box, and a compressor, a condenser and the like providing them on a mounting base, a cold air discharge port and a cold air suction port which are formed in the bottom wall of the thermal insulating housing, the bottom wall being also a ceiling of the machine room, and communicate the interiors of the storage room and the machine room with each other, positioning means for positioning the cooling unit in the machine room such that the discharge side and the suction side of the cooling chamber correspond to the lower sides of the cold air discharge port and the cold air suction part, and pushing-up means for causing the cooling unit to be pushed up toward the bottom wall of the thermal insulating housing by abutting against the lower surface of the mounting base on its both sides or front and rear sides with respect to a direction inserting the cooling unit into the machine room, wherein the pushing-up means comprises pivotally movable pushing-up members provided respectively over from the front side to the rear side in the machine room at positions corresponding to both the sides of the cooling unit, and operating arms provided on the front side of the pushing-up members for pivotally moving the pushing-up members, and wherein the pushing-up members are pivotally moved in a direction pushing up the mounting base by causing the operating arms from their upright standing state to fall down toward the mounting base.
