PURPOSE: To obtain a comfortable use sense by eliminating air of high humidity by placing a ventilation substance having many through-holes and having rubber elasticity between the outside surface and the inside surface of a seat back part or a seat part, and bringing the ventilation substance concerned to piping to an aspirator.
CONSTITUTION: A dehumidifying part consisting of a module in which a pipe 1 having rubber elasticity is arranged by one layer is sewn on a seat back part 14 and a seat part 15, or stuck with an adhesive agent, etc., and each dehumidifying part and a vacuum pump 6 are connected by a piping 7. Also, an elastic body 3 holds the module and a foaming material 2, and the pipe 1, the foaming material 2, and the elastic body 3 are fixed to cloth 8 having permeability. When the vacuum pump 6 is driven, air in the pipe 1 is sucked and eliminated, therefore, wet and high temperature air which comes into contact with the seat back part 14 and the seat 15 is sucked and eliminated through the foaming material 2 and the cloth 8 having permeability. Also, it is also possible to eliminate air which comes into contact with the seat back part 14 and the seat part 15 by feeding out new air whose temperature and humidity are controlled by connecting to a compressor instead of the vacuum pump 6.
