PROBLEM TO BE SOLVED: To provide a safety device which can prevent the breakdown of a system when the system is failed.SOLUTION: A safety device is arranged at a safety device attachment fluid passage L4. The safety device 4 has a cooling part 41(L1) which is constituted of a part of a heated fluid passage L1 in which a heated fluid A1 circulates, and cools a part of the safety device attachment fluid passage L4 by the circulation of the heated fluid A1 to the heated fluid passage L1, and a fusion member 42 which is arranged inside a part of the safety device attachment fluid passage L4 which is cooled by the cooling part 41. When the circulation of the heated fluid A1 in the cooling part 41 is stopped, the fusion member 42 is fused by a rise of a temperature of the safety device attachment fluid passage L4, and the safety device attachment fluid passage L4 is blocked. |
