PROBLEM TO BE SOLVED: To downsize a changeover water stop valve, with a flow rate secured.SOLUTION: An outside stationary cylinder 20 has, as opening parts, a first opening part 21A overlapped with a flow passage hole 31 in a case where an inside rotational cylinder 30 is at a water discharge position where shower water is discharged, and a second opening part 21B overlapped with the flow passage hole 31 in a case where the inside rotational cylinder 30 is at a water discharge position where faucet water is discharged, wherein the first opening part 21A and the second opening part 21B are provided on the same circumference, and between the first opening part 21A and the second opening part 21B, provided is a wall part 21C configured to close the flow passage 31 in a case where the inside rotational cylinder 30 is at a water stop position.SELECTED DRAWING: Figure 2
【課題】流量を確保しつつ、切換止水弁を小型化することができる。【解決手段】外側固定筒２０は、開口部として、内側回転筒３０がシャワー吐水用の吐水位置にあるときに流路穴３１と重なる第１開口部２１Ａと、内側回転筒３０がカラン吐水用の吐水位置にあるときに流路穴３１と重なる第２開口部２１Ｂとを有し、第１開口部２１Ａと第２開口部２１Ｂは同一円周上に設けられるとともに、第１開口部２１Ａと第２開口部２１Ｂとの間には、内側回転筒３０が止水位置にあるときに流路穴３１を塞ぐ壁部２１Ｃが設けられている。【選択図】図２
