PROBLEM TO BE SOLVED: To provide a fluid selector valve which can be switched among plural states with a simple configuration.SOLUTION: A fluid selector valve 130 includes: a first elastic tube 111 through which first fluid flows a second elastic tube 112 through which second fluid flows a third elastic tube 113 connected to the first elastic tube and the second elastic tube in one end and a selector member 131 which can be switched among a first state in which the first elastic tube is constricted and the second fluid is made to flow into the third elastic tube, a second state in which the second elastic tube is constricted and the first fluid is made to flow into the third elastic tube, a third state in which both of the first elastic tube and the second elastic tube are constricted and flowing of the fluid into the third elastic tube is interrupted, and a fourth state in which neither the first elastic tube nor the second elastic tube is constricted and the first fluid and the second fluid are made to flow into the third elastic tube, by displacing protrusions 131a and 131b.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】簡易な構成で、複数の状態を切り替える流体切替弁を提供する。【解決手段】流体切替弁130は、第1流体を流通させる第1弾性チューブ111と、第2流体を流通させる第2弾性チューブ112と、一端において第1弾性チューブおよび第2弾性チューブに接続された第3弾性チューブ113と、凸部131a,131bを変位させることにより、第1弾性チューブを狭窄して第2流体を第3弾性チューブに流通させる第1状態と、第2弾性チューブを狭窄して第1流体を第3弾性チューブへ流通させる第2状態と、第1弾性チューブおよび第2弾性チューブを共に狭窄して第3弾性チューブへの流体の流入を遮断する第3状態と、第1弾性チューブおよび第2弾性チューブを共に狭窄せずに第1流体と第2流体を第3弾性チューブへ流通させる第4状態に切り替える切替部材131とを備える。【選択図】図3
