Abstract
A liquid inlet located in the lower position of a liquid passage is sealed with the valve guide of a valve body. The lever pushes the valve guide of the valve body to open up the liquid inlet. A pair of fixing arms is provided on the edge of the lever. An insertion hole of the pivot installed in a protruding manner or two sidewalls of the liquid passage is formed on each fixing arm. When moving the lever in the direction opposite to operation around each fixing arm, the boss member is abutted on sidewalls to widen the gap between each fixing arm to remove the insertion hole from the pivot. This makes it easy to take apart and assemble the structured parts of the plug and makes it washable in every nook and corner inside the plug structure.
