To immediately shift from water cut-off mode to water supply mode without causing a time lag, thereby securing improved usability and operational feeling (comfortable operability).SOLUTION: An antifreeze water tap post comprises: an on-off valve mechanism Vf that blocks a water passage R at a lowest descending position Xd of a spool part 4s and opens the water passage R with rising variation from the lowest descending position Xd of the spool part 4s; an inner discharge passage 6 formed inside the spool part 4s and including an inflow port 6i positioned on a lower side and an outflow port 6e positioned on an upper side; a check valve mechanism Vnf that is attached to the inner discharge passage 6 and that blocks the inner discharge passage 6 with a predetermined water pressure of tap water W flowing in from the inflow port 6i; and a spool valve mechanism Vm that allows an outer discharge passage 7 facing outside and the outflow port 6e to communicate with each other at the lowest descending position Xd of the spool part 4s and allows the inflow port 6i and the water passage R to communicate with each other in a predetermined variation section Li of the spool part 4s that moves upward from the lowest descending position Xd.SELECTED DRAWING: Figure 1
【課題】 止水から給水する際に時間差を生じることなく即座に移行させ、良好な使い勝手や操作感（快適操作性）を確保する。【解決手段】 スプール部４ｓの最下降位置Ｘｄで通水路Ｒを遮断し、かつ最下降位置Ｘｄからのスプール部４ｓの上昇変位により通水路Ｒを開放する開閉弁機構部Ｖｆと、スプール部４ｓの内部に形成し、かつ下側に位置する流入口６ｉと上側に位置する流出口６ｅを有する内排出路６と、この内排出路６に付設し、少なくとも流入口６ｉから流入する水道水Ｗによる所定の水圧により内排出路６を遮断する逆止弁機構部Ｖｎｆと、スプール部４ｓの最下降位置Ｘｄでは外部に臨む外排出路７と流出口６ｅを連通させ、かつ最下降位置Ｘｄから上昇変位するスプール部４ｓの所定の変位区間Ｌｉでは流入口６ｉと通水路Ｒを連通させるスプール弁機構部Ｖｍとを具備する。【選択図】 図１
