PROBLEM TO BE SOLVED: To provide a vehicular seat blower that is able to reduce air-force generation sound resulting from a flow of air flowing in an empty space in a sealing member, and to provide a vehicular seat having the blower.SOLUTION: A blowing unit 20 comprises a blower 21 and a sealing member 50. The blower 21 has an impeller that generates a flow of air, and a blower port 24 that is an opening for circulating the flow of air in a ventilation flue formed in a seat pad. The blower is attached to a vehicular seat along a seat pad in a position where the opening of the ventilation flue provided in the rear surface of the seat pad and a blower-side opening face each other. The sealing member 50 is interposed between the opening of the ventilation flue and the blower port 24 and surrounds a space between the opening of the ventilation flue and the blower port 24, thereby forming a circulation route where a flow of air can circulate. An escape passage 52 for allowing part of a flow of air to circulate inside and outside is provided in a portion connecting the sealing member 50 and the ventilation flue.SELECTED DRAWING: Figure 4

    【課題】シール部材の隙間を流れる気流に起因する空力発生音を低減可能な乗物用シート送風装置、及び当該送風装置を備える乗物用シートを提供する。【解決手段】送風ユニット20は、送風機21とシール部材50とを備える。送風機21は、気流を発生させる羽根車と、当該気流をシートパッド内に形成された通風路に流通させるための開口である送風機口24とを有し、シートパッドの裏面に設けられた通風路の開口と送風機側開口とが向かい合う位置でシートパッドに沿って乗物用シートに装着される。シール部材50は、通風路の開口と送風機口24との間に介在し、通風路の開口と送風機口24との間の空間を囲んで気流が流通可能な流通経路を形成するように構成されている。また、シール部材50と通風路の開口とが接続する接続部分に、気流の一部が内外に流通可能な逃がし流路52が設けられている。【選択図】図4
