PROBLEM TO BE SOLVED: To reduce vertical dimensions of a connection duct in a vehicle seat air conditioner arranged by bending the connection duct in a U shape.SOLUTION: A connection duct 6 comprises a cylindrical skin member 61 formed of a material rich in flexibility to make air-conditioning wind circulate and a plurality of core materials 62 formed of a material which has a higher rigidity than the skin member 61 and arranged along an air flow direction in the skin member to maintain the cross-sectional shape of the skin member 61 to a predetermined shape. The core materials 62 comprise an outer peripheral plate part 621 positioned on the outer peripheral side in a bent part, an inner peripheral plate part 622 positioned on the inner peripheral side in a bent part, and a connection plate part 623 that connects the outer peripheral plate part 621 with the inner peripheral plate part 622 and keep a length in an air flow direction B in the outer peripheral plate part 621 longer than a length in the air flow direction B in the inner peripheral plate part 622.
【課題】接続ダクトをU字状に曲げて配置する車両用シート空調装置において、接続ダクトの上下寸法を小さくする。【解決手段】接続ダクト6は、可撓性に富む材料にて形成され、空調風が流通する筒状の外皮部材61と、外皮部材61よりも剛性の高い材料にて形成され、外皮部材内に空気流れ方向に沿って複数個配置されて外皮部材61の断面形状を所定形状に維持する芯材62とを備えている。芯材62は、曲がり部において外周側に位置する外周板部621と、曲がり部において内周側に位置する内周板部622と、外周板部621と内周板部622とを連結する連結板部623とを備え、外周板部621における空気流れ方向Bの長さは、内周板部622における空気流れ方向Bの長さよりも長くなっている。【選択図】図7
