a pair of left and right cross members that are coupled to the floor panel and that extend in the left-right direction; and
a battery pack, comprising an upper battery and a lower battery, disposed below the floor panel; and
a coupling member that is disposed above the lower battery at a center of the automobile vehicle in the left-right direction in a front view, that extends in the left-right direction, and that is coupled to the left and right cross members in the flat members of the floor panel,
wherein the upper battery is disposed above the lower battery, and wherein the coupling member extends externally to an interior of the tunnel member in the left-right direction.

2. The automobile vehicle according to claim 1 ,
wherein a center of the tunnel member in the left-right direction projects upward,
wherein the upper battery is disposed in the tunnel member, and
wherein the coupling member is coupled to the left and right cross members at locations of the coupling member that are positioned outside of the tunnel member in the left-right direction.

3. The automobile vehicle according to claim 2 ,
wherein the battery pack is attachable to and detachable from the vehicle body from a lower side of the automobile vehicle and is fastened to the vehicle body by bolts and nuts.

4. The automobile vehicle according to claim 3 ,
wherein the coupling member is fastened to the left and right cross members by a bolt and a nut.

5. The automobile vehicle according to claim 4 ,
wherein the vehicle body comprises a pair of left and right side members that extend in the front-rear direction, and
wherein the battery pack comprises a support panel that supports the lower battery, that extends in the left-right direction, and that is fastened on both end sides to the respective left and right side members by a bolt and a nut.

6. The automobile vehicle according to claim 3 ,
wherein the vehicle body comprises a pair of left and right side members that extend in the front-rear direction, and
wherein the battery pack comprises a support panel that supports the lower battery, that extends in the left-right direction, and that is fastened on both end sides to the respective left and right side members by a bolt and a nut.

7. The automobile vehicle according to claim 3 ,
wherein each of the left and right cross members is a seat cross member to which a seat is secured.

8. The automobile vehicle according to claim 7 ,
wherein the automobile vehicle comprises a plurality of the seat cross members that are arranged in the front-rear direction at intervals, and
wherein the automobile vehicle comprises a plurality of the coupling members that are coupled to the seat cross members.

9. The automobile vehicle according to claim 2 ,
wherein each of the left and right cross members is a seat cross member to which a seat is secured.

10. The automobile vehicle according to claim 9 ,
wherein the automobile vehicle comprises a plurality of the seat cross members that are arranged in the front-rear direction at intervals, and
wherein the automobile vehicle comprises a plurality of the coupling members that are coupled to the seat cross members.

11. The automobile vehicle according to claim 1 ,
wherein the battery pack is attachable to and detachable from the vehicle body from a lower side of the automobile vehicle and is fastened to the vehicle body by bolts and nuts.

12. The automobile vehicle according to claim 11 ,
wherein the coupling member is fastened to the left and right cross members by a bolt and a nut.

13. The automobile vehicle according to claim 12 ,
wherein the vehicle body comprises a pair of left and right side members that extend in the front-rear direction, and
wherein the battery pack comprises a support panel that supports the lower battery, that extends in the left-right direction, and that is fastened on both end sides to the respective left and right side members by a bolt and a nut.

14. The automobile vehicle according to claim 11 ,
wherein the vehicle body comprises a pair of left and right side members that extend in the front-rear direction, and
wherein the battery pack comprises a support panel that supports the lower battery, that extends in the left-right direction, and that is fastened on both end sides to the respective left and right side members by a bolt and a nut.

15. The automobile vehicle according to claim 11 ,
wherein each of the left and right cross members is a seat cross member to which a seat is secured.

16. The automobile vehicle according to claim 15 ,
wherein the automobile vehicle comprises a plurality of the seat cross members that are arranged in the front-rear direction at intervals, and
wherein the automobile vehicle comprises a plurality of the coupling members that are coupled to the seat cross members.

17. The automobile vehicle according to claim 1 ,
wherein each of the left and right cross members is a seat cross member to which a seat is secured.

18. The automobile vehicle according to claim 17 ,
wherein the automobile vehicle comprises a plurality of the seat cross members that are arranged in the front-rear direction at intervals, and
wherein the automobile vehicle comprises a plurality of the coupling members that are coupled to the seat cross members.

19. An automobile vehicle comprising:
a vehicle body that comprises a floor panel with a tunnel member, and a pair of left and right cross members that are coupled to the floor panel and that extend in a left-right direction; and
a battery pack disposed below the floor panel,
wherein the battery pack comprises a lower battery, an upper battery disposed above the lower battery, and a coupling member that is disposed above the lower battery at a center of the automobile vehicle in the left-right direction in a front view, that extends in the left-right direction, and that is coupled on both end sides of the coupling member to the left and right cross members, respectively, and
wherein the coupling member is coupled to the left and right cross members at locations of the coupling member that are positioned outside of an interior of the tunnel member in the left-right direction.
