PROBLEM TO BE SOLVED: To provide a blowing device of a vehicular seat configured to blow air to a seated surface of a seat by a blower to ventilate a circumstance around an occupant, which is improved in the problem that a pad material at a blower installation site lacks strength, by forming at least parts of air passages at an upstream side and at a downstream side of the blower, which are formed in the pad material, of one passage, to suppress the number of air passages which are decentrally arranged at the blower installation site.SOLUTION: An air passage comprises: a plurality of first air blowing paths 211a that suction air through a through-hole 211b opened onto a seat surface; a second air blowing path 211c that exhausts air to the outside of a seat; and a communication path 211b that communicates the first air blowing paths with the second air blowing path. In the communication path are provided a shield plate 24, in which a space near the first air blowing paths and a space near the second air blowing path in the communication path are separated from each other so that the first air blowing paths and the second air blowing path communicated with the communication path are separated from each other and a communication port is formed so as to communicate partially the separated spaces near both sides with each other, and a blower 23 that blows air through the communication port.SELECTED DRAWING: Figure 2
【課題】シートの着座表面に送風機により空気を流して、乗員周辺の環境の換気を行うものにおいて、パッド材に形成される送風機の上流側と下流側の各空気通路の少なくとも一部を一つの通路にて形成することにより、送風機設置部位において分散配置される空気通路の数を抑制して、当該部位のパッド材の強度が不足する問題を改善する。【解決手段】空気通路は、シート表面上に開けられた貫通孔211bから空気を吸い込む複数の第1送風路211aと、シート外部に排気を行う第2送風路211cと、第1送風路を第2送風路に連通させる連通路211dとを備え、連通路には、連通路につながる第1送風路及び第2送風路が互いに分離されるように、連通路における第1送風路側の空間と第2送風路側の空間を切り離し、しかも切り離された両側の空間を部分的に連通するように連通口を形成された遮蔽板24と、連通口を通じて送風を行う送風機23とが設けられている。【選択図】図2
