PROBLEM TO BE SOLVED: To provide a sleeping bag capable of suppressing the waste of an energy resource by air-conditioning a minimum necessary space for a person to rest. SOLUTION: This sleeping bag is constituted by connecting an air conditioner 3 which has a stirling refrigerator 13, a ventilation passage 15, a heat exchanger 20 heat-transmittibly connected to the stirling refrigerator 13 and provided exposedly to the ventilation passage 15, and a blower 21 sending air of a space S to the heat exchanger 20; to a sleeping bag body 2 having the space S for a person to lie in its inside. The blower 21 circulates at least a part of air between the space S and the heat exchanger 20 via the ventilation passage 15 so as to air-condition the space S alone in the sleeping bag body 2. The stirling refrigerator 13 itself can be operated by a small electric power to suppress the waste of the energy resource and the environmental pollution. COPYRIGHT: (C)2007,JPO&INPIT
