Abstract:
A drain plug device comprising:a hollow ascending/descending member connected to a plug lid, the ascending/descending member being configured to move up and down in a guiding part arranged at a central part in a drain port of a vessel; a supporting shaft insertable into the ascending/descending member; a releasing member connected at a first end to an operating part arranged in the vessel and, at a second end, to the plug lid, the releasing member comprising an inner wire operated by a pushing operation of the operating part; and an engaging mechanism positioned between a lower end of the supporting shaft and the guiding part, the engaging mechanism being configured to engage the lower end of the supporting shaft, holding the supporting shaft immobile; wherein a forward motion of the inner wire abuts a lower end of the inner wire against the supporting shaft, causing a downward force against the immobile supporting shaft, resulting in an upward force against the ascending/descending member, which moves upward and lifts the connected plug lid to open the drain port.
