Abstract
In this battery pack arrangement structure, since a case main body of a battery case is made of a metal by die-casting, not only is it possible to reduce the number of components and the weight by forming, integrally with the case main body, a cross member protruding upward from a case bottom wall and extending in the vehicle width direction and a second fixing portion protruding outward in the vehicle width direction from a case side wall, but it is also possible to enhance the side collision resistance by increasing the strength of the case main body including the cross member and the second fixing portion. Moreover, since the second fixing portion protruding outward in the vehicle width direction from the case side wall is fixed to a floor frame, due to the collision load of a side collision being directly transmitted from the floor frame to the cross member of the case main body and supported, it is possible to ensure the side collision resistance even when the strength of the floor frame is decreased so as to lighten the weight.
