PURPOSE:To facilitate stowing by fabricating a curtain capable of being stowed by rolling or so with a sheet provided on its one side with a heater and made into a bag shape, sending air into and out of the bag-like portion, and controlling the heater with the air pressure. CONSTITUTION:A curtain 12 capable of being stowed is constituted with at least two sheet members with one side of the sheet member provided with a heater and made into a bag shape. Air is sent into the bag-shaped portion to swell up to an appropriate thickness to improve heat insulation effect. At the time of stowing, air is discharged to make the curtain flat and thin. A device is provided for controlling electric power according to the air pressure in the bag portion. This facilitates stowing of the curtain for both summer and winter use. |
