ABSTRACT:
A draining plug device includes a plug lid which opens and closes a draining port and is installed on a support provided in a water drainage cylinder, a remote operating portion which is directly connected to the support and the plug lid by means of a flexible wire-like connection, and an opening and closing holding mechanism which provides guidance and support so that an operational force generated by pushing down on the remote operating portion is transmitted to the support and the plug lid. The plug lid can be alternated between an opened state and a closed state by pushing down on the operating portion.
