Zusammenfassung:To obtain a flow passage selector valve comprising a simple structure, and having a quick and sure flow passage changeover function.SOLUTION: A flow passage selector valve B comprises: a case C; a fluid supply part 1 for supplying a fluid W to an internal space of the case C; a valve body V1 having a first circulation part R1 for making the fluid W flow to a specified circulation destination, and a first opposing face F1 at which the first circulation part R1 is opened; a second opposing face F2 of the case C opposing to the first opposing face F1; an energization member P1 for pressing the first opposing face F1 to the second opposing face F2; a drive part K for rotationally driving the valve body V1; and a plurality of second circulation parts arranged at the second opposing face F2. A fluid supply part 1 includes: a recess 4 which is opened at a space on a side opposite to the first opposing face F1 with respect to the valve body V1 out of the internal space, and in which the first circulation part R1 is opened at the second opposing face F2 in a part of the first opposing face F1 to oppose to the second circulation part; and a communication part 5 formed at a part of the recess 4 in a view orthogonal to the first opposing face F1, and making the recess 4 and the internal space communicate with each other.SELECTED DRAWING: Figure 1 【課題】簡便な構造を備え迅速かつ確実な流路切替機能をもつ流路切替バルブを得る。【解決手段】ケースCと、ケースCの内部空間に流体Wを供給する流体供給部1と、流体Wを特定の流通先に流通させる第1流通部R1および第1流通部R1が開口する第1対向面F1を有する弁体V1と、第1対向面F1に対向するケースCの第2対向面F2と、第1対向面F1を第2対向面F2に押し付ける付勢部材P1と、弁体V1を回転駆動する駆動部Kと、第2対向面F2に設けられた複数の第2流通部と、を備え、流体供給部1が、内部空間のうち弁体V1に対して第1対向面F1の反対側の空間に開口し、第1流通部R1が、第1対向面F1の一部において第2対向面F2に開口し、第2流通部と対向する凹部4と、第1対向面F1への直交視において凹部4の一部に形成され凹部4と内部空間とを連通する連通部5と、を備えた流路切替バルブB。【選択図】図1
