3. The vehicle-body structure of the electric automotive vehicle of claim 2 , wherein said floor-side cross member and said battery-side cross member respectively overlap a pair of right-and-left side sills which are provided to extend in the vehicle longitudinal direction at both end portions, in the vehicle width direction, of said floor panel in the vehicle side view.
4. The vehicle-body structure of the electric automotive vehicle of claim 3 , wherein said floor-side cross member and said battery-side cross member are provided alternately in the vehicle longitudinal direction.
5. The vehicle-body structure of the electric automotive vehicle of claim 2 , wherein said floor-side cross member and said battery-side cross member are provided alternately in the vehicle longitudinal direction.
6. The vehicle-body structure of the electric automotive vehicle of claim 1 , wherein said floor-side cross member is attached to an upper face of said floor panel.
7. The vehicle-body structure of the electric automotive vehicle of claim 6 , wherein said floor-side cross member and said battery-side cross member are provided alternately in the vehicle longitudinal direction.
8. The vehicle-body structure of the electric automotive vehicle of claim 1 , wherein said floor-side cross member and said battery-side cross member are provided alternately in the vehicle longitudinal direction.
9. The vehicle-body structure of the electric automotive vehicle of claim 1 , wherein said floor-side cross member and said battery-side cross member respectively overlap a pair of right-and-left side sills which are provided to extend in the vehicle longitudinal direction at both end portions, in the vehicle width direction, of said floor panel in the vehicle side view.
10. A vehicle-body structure of an electric automotive vehicle in which a motor for vehicle driving is provided and a battery case where a battery to supply electric power to the motor for vehicle driving is stored is arranged below a floor panel, comprising:
a floor-side cross member attached to the floor panel and extending in a vehicle width direction along the floor panel; and
a battery-side cross member provided at the battery case and extending in the vehicle width direction,
wherein said floor-side cross member and said battery-side cross member are offset from each other in a vehicle longitudinal direction in a vehicle side view, and
wherein said floor-side cross member and said battery-side cross member respectively overlap a pair of right-and-left side sills which are provided to extend in the vehicle longitudinal direction at both end portions, in the vehicle width direction, of said floor panel in the vehicle side view.
11. The vehicle-body structure of the electric automotive vehicle of claim 10 , wherein said floor-side cross member and said battery-side cross member are provided alternately in the vehicle longitudinal direction.
12. A vehicle-body structure of an electric automotive vehicle in which a motor for vehicle driving is provided and a battery case where a battery to supply electric power to the motor for vehicle driving is stored is arranged below a floor panel, comprising:
a floor-side cross member attached to the floor panel and extending in a vehicle width direction along the floor panel; and
a battery-side cross member provided at the battery case and extending in the vehicle width direction,
wherein said floor-side cross member and said battery-side cross member are offset from each other in a vehicle longitudinal direction in a vehicle side view,
wherein said floor-side cross member is attached to an upper face of said floor panel, and
