Abstract

PURPOSE: To prevent the flowing out of a liquid within a liquid storage tank by making it possible to confirm the opening of the drain plug of a liquid storage tank such as a bath tub or the like.
CONSTITUTION: A drain plug 1 is arranged to be able to fit to an outlet port 3 provided at the bottom part 2 of the liquid storage tank. A magnet 4 is secured to the bottom part of the drain plug 1. A reed switch 5 is fixed to a supporting part provided at the outlet port 3, and the drain plug 1 is opposed to the magnet 4 in a state where the drain plug 1 is fitted to the outlet port 3. A lead wire 7 is connected to the read switch 5, and connected to the outside announciator. When the drain plug 1 is fitted in the outlet port 3 and the magnet 4 reaches a constant position, the read switch 5 operates and a current flows to a lead wire 7 and the opening of the drain plug can be confirmed.
