Vehicular seat air-conditioning system

A vehicular seat air-conditioning system which blows out from a seat cool air which is supplied from an in-door air-conditioning unit which air-conditions a cabin space, said vehicular seat air-conditioning system comprising:

• a blower which generates blown air,
• a flexible bellows forming an intake duct which is connected to an intake side of the blower;
• a seat air-conditioning duct which is connected to the in-door air-conditioning unit and in which cool air which was cooled by the in-door air-conditioning unit flows;
• and
• a box-shaped part which is formed by a separate member from chassis members forming the cabin space and which is connected to a downstream side end of the seat air-conditioning duct,
• the box-shaped part having side walls which extend in a vertical direction and a bottom which closes a space surrounded by the side walls from the lower side,
• the top ends of the side walls forming an opening part which opens facing the upper side in the vertical direction, and
• an upstream side end of the intake duct being inserted into the inside of the box-shaped part through the opening part without being fitted and fixedly connected to the box-shaped part of the seat air conditioning duct so that the insertion of the intake duct into the inside of the box-shaped part is maintained within an adjustable range of the position of the seat in a longitudinal direction, wherein
• the upstream side end of the intake duct is located closer to the bottom of the box-shaped part than the opening part of the box-shaped part.
