To provide a selector valve which can be thinned in a thickness direction of a seat and the seat including the selector valve.SOLUTION: A selector valve 500 includes: an annular base 512 which is formed into a flat plate shape and an annular shape surrounding a center opening; and a plurality of valve elements 520 which are supported by the annular base 512 so as to be rotatable with respect to the annular base 512 around a rotary shaft A arranged with a space around the center opening and around the rotary shaft A orthogonal to the annular base 512. Each valve element 520 of the plurality of valve elements 520 is rotatable around the rotary shaft A between a closing attitude in which the valve element comes into contact with the valve element 520 adjacent to the valve element 520 and overlaps the center opening in a direction parallel to an axial direction of the rotary shaft A so as to close the center opening and an opening attitude in which the valve element retreats to a position where the valve element does not overlap the center opening in the direction parallel to the axial direction of the rotary shaft A so as to open the center opening.SELECTED DRAWING: Figure 5
【課題】シートの厚さ方向に薄型化すること可能な切替弁及び切替弁を備えるシートを提供すること。【解決手段】切替弁500は、平板状でかつ中央開口を取り囲む環状に形成された環状ベース512と、中央開口の周囲に間隔を置いて配置された回転軸Aであって環状ベース512に対して直交する前記回転軸Aまわりに環状ベース512に対して回転可能となるように環状ベース512に支持された複数の弁体520と、を備える。複数の弁体520の各弁体520は、当該弁体520に隣接する弁体520と接触するとともに回転軸Aの軸方向と平行な方向に中央開口と重なることによって中央開口を閉塞する閉塞姿勢と、回転軸Aの軸方向と平行な方向に中央開口と重ならない位置に退避することによって中央開口を開放する開放姿勢と、の間で回転軸Aまわりに回動可能である。【選択図】図5
