A refrigerator for vehicles has a cooling unit and a cool-keeping container adapted to be detachably connected to the cooling unit and contain goods to be cooled. The cooling unit includes a refrigerator evaporator connected to a refrigeration cycle of an automotive airconditioning refrigeration cycle on a vehicle and a coldness accumulating medium supported in heat exchange relationship with the evaporator. During evaporator operation, the coldness is accumulated in the coldness-accumulating medium and simultaneously transferred to the goods in the cool-keeping container. When the goods are cooled to a desired temperature, the cool-keeping container can be disconnected from the cooling unit and taken out of the vehicle with a heat insulating lid closing an opening formed in the container for the insertion and removal of the goods into and out of the container.
