PROBLEM TO BE SOLVED: To provide a high pressure tank device 10 which covers a periphery of a high pressure tank 12 and prevents the high pressure tank 12 to be exposed to flame from the exterior.SOLUTION: A tank protection container 20 includes: a cover member 22 which covers a periphery of a high pressure tank 12 and forms a storage space 20S; and a storage tank 28 which is provided at a lower part of the cover member 22. The cover member 22 includes a bottom wall 23b which inclines relative to a horizontal surface, and the bottom wall 23b includes a first discharge port 28a disposed at the lowest position. The storage tank 28 includes: a storage chamber 28S which is formed so as to accumulate a liquid flowing out from the storage space 20S through the first discharge port 28a and close the first discharge port 28a when the accumulated liquid is positioned at a given liquid level; and a second discharge port 28b which is connected with the storage chamber 28S and discharges the liquid to the exterior when the liquid accumulated in the storage chamber 28S exceeds the given liquid level. |
