を特徴とする排水栓。 This drain plug is attached to the drain port 9 of the hot water tank 6, and the plug body 11 is provided with a drain channel 12 that communicates the inside of the hot water tank 6 with the outside via the drain port 9,
This drainage channel 12 is provided with a valve seat 13, and
A valve body 14 is disposed so as to be able to come into contact with and separate from the valve seat 13, and a valve body actuating means 18 made of a shape memory material for operating the valve body 14 is disposed at a position closer to the bath 6 than this valve body 14. The valve body operating means 18
Due to the shape change, the valve body 14 is brought into contact with the valve seat 13 when the ambient temperature exceeds a specific temperature, and the valve body 14 is separated from the valve seat 13 when the ambient temperature falls below the above temperature. A drain plug characterized by being configured as follows.
