To obtain a high-pressure vessel mounting structure which can improve heat transmission efficiency to a fusible plug valve when a lower part of a vehicle becomes high in a temperature, in a structure in which a high-pressure vessel is mounted to the lower part of the vehicle.SOLUTION: A vehicle 10 includes: a vessel main body 30 mounted to a lower part of the vehicle; a manifold 34 having a general flow passage 34A for making the vessel main body 30 and a valve 36 communicate with each other and an exhaust gas flow passage 34B which is branched from the general flow passage 34A; a fusible plug valve 50 for blocking the exhaust gas flow passage 34B, releasing the exhaust gas flow passage 34B when at least partially fused, and discharging a high-pressure gas which is accommodated in the vessel main body 30; a case 12 including a lower face part 16 for covering the vessel main body 30 and the manifold 34 from a lower side of the vehicle, and arranged while making a bead 20 formed by raising a part of the lower face part 16 to an upper side of the vehicle approximate the fusible plug valve 50; and a communication port 22 formed in a region opposing the fusible plug valve 50 of the beam 20, and making a space below a vehicle floor and the fusible plug valve 50 communicate with each other.SELECTED DRAWING: Figure 4

    【課題】車両下部に搭載された高圧容器が搭載された構造において、車両下部が高温になった場合に溶栓弁への伝熱効率を向上させることができる高圧容器搭載構造を得る。【解決手段】車両10は、車両下部に搭載された容器本体30と、容器本体30とバルブ36とを連通する一般流路34Aと、一般流路34Aから分岐した排ガス流路34Bとを備えるマニホールド34と、排ガス流路34Bを閉塞させると共に、少なくとも一部が溶融された場合に、排ガス流路34Bを開放して容器本体30に収容された高圧ガスを排出させる溶栓弁50と、容器本体30及びマニホールド34を車両下方側から覆う下面部16を含み、下面部16の一部を車両上方側へ隆起させてなるビード20を溶栓弁50に近づけて配置したケース12と、ビード20における溶栓弁50と対向する部位に形成され、車両床下の空間と溶栓弁50とを連通させる連通口22と、を有する。【選択図】図4
