<Effects of the invention> In the present invention, there is no need to separately provide a dispensing mechanism for dispensing liquid and a liquid volume display mechanism for indicating the volume of liquid, and both mechanisms can be provided integrally. Furthermore, complicated work can be eliminated, assembly can be performed easily and reliably, and costs can be significantly reduced, and the number of defective products can be reduced.

That is, the inside of the shaft that moves up and down with the valve body by the operating lever is always in communication with the liquid passage of the faucet body, and the inside of this shaft and the inside of the hollow pipe are communicated through the hollow shaft, and the shaft is has a bellows part that prevents the vertical movement of the hollow pipe and does not restrict the vertical movement of the shaft along with the shaft, so there is a narrow space between the inner container and the outer case, and there is only a small amount of the faucet body that protrudes beyond the outer case. Even though the portion of the faucet main body that communicates with the liquid passage is limited to a very narrow space, the assembly is extremely simple and can be easily and reliably assembled. In addition, it is possible to reduce the number of defective products because the sealing performance of the portions of the faucet main body communicating with the liquid passage, the shaft rod, etc. can be visually confirmed, as well as cumbersome work is eliminated.
