PROBLEM TO BE SOLVED: To efficiently cool a drink at low cost by forming a flow passage flowing with a coolant near an outer surface of a drinking vessel stored in a cup holer for a vehicle. SOLUTION: In the cup holder for the vehicle, a helical tube 20 flowing with the coolant is arranged in a recession part 10 of the cup holder for storing the drinking vessel 5. The tube 20 is vertically expanded/contracted by the flow of the coolant and an inner diameter of the tube 20 becomes small at expansion to be closely adhered to an outer peripheral surface of the vessel 5. Thereby, heat exchange of the drink and the coolant is promoted and the drink can be efficiently cooled. COPYRIGHT: (C)2007,JPO&INPIT
