To provide a high pressure tank-loading structure capable of inhibiting the inner pressure elevation of a high pressure tank when a vehicle is heated from the outside thereof by delaying the heat transfer to the high pressure tank.SOLUTION: A high pressure tank-loading structure 10 comprises: a tank storage part 26 provided at a vehicle lower side in the floor panel 24 of a vehicle compartment 22 and storing a high pressure tank 20; an undercover 56 provided at a vehicle lower side of the tank 20 in the tank storage part 26 to form a part of the bottom face of a vehicle 12 by the face of the vehicle lower side; and a heat deformation part 62 which is formed at one end part of the undercover 56 in a vehicle horizontal direction, is deformable or displaceable toward the vehicle lower side by heating and expands a space SP between a portion of the vehicle lower side in the tank 20 and the undercover 56.SELECTED DRAWING: Figure 5

    【課題】高圧タンクへの伝熱を遅延させることにより、車両が車両外側から加熱された際の高圧タンクの内圧の上昇を抑制できる高圧タンク搭載構造を提供する。【解決手段】高圧タンク搭載構造10として、車室22のフロアパネル24の車両下方側に設けられると共に高圧タンク20が収容されるタンク収容部26と、タンク収容部26において高圧タンク20の車両下方側に設けられると共に車両下方側の面が車両12の底面の一部を形成するアンダカバー56と、アンダカバー56の車両水平方向の一端部に形成されると共に加熱により車両下方側へ向けて変形又は変位可能とされ、車両下方側へ向けて変形又は変位することにより高圧タンク20の車両下方側の部分とアンダカバー56との間の空間SPを拡張する熱変形部62と、を備える。【選択図】図5
