The invention provides a vehicle upper structure capable of avoiding rigidity reduction caused by deformation due to thermal expansion difference. The vehicle upper structure includes: a roof panel provided in an upper portion of a vehicle body and made of aluminum; a roof rail provided on the outside of the roof panel in the vehicle width direction and extending in the front-rear direction of the vehicle; and an outer cross member provided below the roof panel in the vehicle up-down direction and extending in the vehicle width direction, the outer cross member being joined to the roof rail at an outer end portion in the vehicle width direction, the outer cross member being made of iron, and the outer cross member being provided in the vehicle up-down direction and extending in the vehicle width direction. An inner cross member is provided above the outer cross member in the vertical direction of the vehicle, the rigidity of the inner cross member is higher than the rigidity of the roof panel, the rigidity of the inner cross member is lower than the rigidity of the outer cross member, and the inner cross member is joined to the roof panel.

    本发明提供一种车辆上部结构,能够避免热膨胀差造成的变形而导致刚性下降。车辆上部结构包括:车顶板,设置于车体上部,且由铝制成;车顶纵梁,设置于所述车顶板在车宽方向上的外侧,且沿着车辆前后方向延伸;以及外横梁件,设置于所述车顶板在车辆上下方向上的下方,且沿着所述车宽方向延伸,所述外横梁件在所述车宽方向上的外侧端部与所述车顶纵梁接合,其中所述外横梁件由铁制成,且在所述外横梁件的所述车辆上下方向的上方设置有内横梁件,所述内横梁件的刚性较所述车顶板的刚性高、且所述内横梁件的刚性较所述外横梁件的刚性低,所述内横梁件与所述车顶板接合。
