Claims

[Scope of utility model registration request]

In a bathtub to which piping from an outer pot is connected, a bottomed cylindrical on-off valve is installed inside a bottomed case that has a window that can be brought into contact with the opening for connecting the piping of the bathtub. A shape memory alloy is arranged movably between the inner surface of the on-off valve and the window of the case, and further between the outside of the on-off valve and the bottom of the case opposite to the side where the window is provided. A bathtub heat radiation prevention device comprising a spring disposed between the opening and closing valve, and a push button for moving the on-off valve exposed to the outside of the case through the bottom.
