PROBLEM TO BE SOLVED: To provide an anti-freezing faucet post which surely opens/closes a water passage and a drain passage in a more reasonable mode, which can prevent water leakage more surely and which can perform an operation of water discharge and drainage more easily.SOLUTION: A water passing valve mechanism 10 including a drainage mechanism, a rising water passage 30, a water outlet part 50, and an operation part 40 are provided. The water passing valve mechanism 10 includes: a water passage valve body 13 which includes a water inlet 12 and a water passage 15; and a spool valve 20 which is disposed so as to move vertically in a required length range by being fitted in a sleeve part 16 provided inside the water passing valve body 13. The spool valve 20 includes a water passing opening/closing valve part 21 provided at a lower end part and capable of being located below so as to close the water inlet 12, a drainage opening/closing valve part 22 for opening/closing a drainage communication port which communicates a drain passage 18 and the water passage 15 by being interlocked with this, and a seal part 25 of the spool which can maintain a state of being fitted and sealed, and it is operated by the operation part 40 by being linked via an operation shaft body 35.SELECTED DRAWING: Figure 1 |
