  • Patent number: 10300788
    Abstract: A vehicle includes an electrical device in which a high-voltage part is disposed within a case, and a fuel tank. The high-voltage part is disposed near a first side end of the case in a vehicle width direction. The fuel tank has a first end portion in the vehicle width direction and a second end portion opposite to the first end portion. When a collision load equal to or greater than a predetermined value is applied to the fuel tank from the outside in a vehicle front-rear direction, the fuel tank is configured to be horizontally rotated about the first end portion of the fuel tank, and the second end portion of the fuel tank is configured to contact the second side end of the electrical device.
