A pipe switching section formed in a hot water supply pipe and equipped with a supply port and a discharge port, and a pipe switching section that is slidably disposed in the pipe switching section and selectively connects the supply port and the discharge port. If the temperature of the hot water is lower than a preset temperature, the valve body is stretched between the valve body to be closed and the valve body and the pipe line switching section, and the valve body is slid in one direction to open the outlet port. and an elastic body made of a shape memory alloy that deforms when the temperature exceeds the set temperature and slides the valve body in the other direction to close the supply port. 2. The hot water blowout prevention device according to claim 1,
A hot water blowout prevention device characterized in that a bias elastic body is stretched between a valve body and a pipe switching section. 3. The hot water spout prevention device according to claim 1,
A hot water spout prevention device characterized by being provided with a lock mechanism that locks a supply port from being blocked by a valve body.
