置。[Scope of Claim for Utility Model Registration] A valve seat formed in the middle of a hot water supply pipe, a water stop valve provided opposite to the valve seat from the downstream side of the pipe so as to be movable forward and backward, and the water stop valve. from the downstream side of the pipeline, a normally closed spring that presses against the valve seat against the water pressure in the pipeline to close the valve, and the water stop valve that is driven against the biasing force of the spring. and a drive motor that opens the valve, and further drives the drive motor in the valve closing direction from the state where the water stop valve is in close contact with the valve seat, and absorbs the surplus drive amount by that amount. A water stop valve device for a water heater, characterized in that a means is provided.
