5 . The vehicle body rear structure of claim 2 , wherein the cross member includes:

a main cross surface directly in contact with the support portion; and

a cross member horizontal surface disposed toward a portion where the support portion and the internal connection are connected.

6 . The vehicle body rear structure of claim 2 , wherein the rear protruding portion includes:

a first mounting protruding portion connected to a vehicle body rear module; and

a second mounting protruding portion connected to a rear sub-frame.

7 . The vehicle body rear structure of claim 2 ,

wherein the cabin includes a partition panel formed at a rear thereof, and

wherein the rear module mounting panel includes a front connection portion connected to the partition panel.

8 . The vehicle body rear structure of claim 7 , wherein the rear module mounting panel further includes a module connection portion for connecting the mounting portion and the front connection portion.

9 . The vehicle body rear structure of claim 8 , wherein the rear module mounting panel further includes a protrude connection portion formed to protrude to the mounting portion and the module connection portion.

10 . The vehicle body rear structure of claim 8 , further including a battery cover disposed between the cabin and the cross member, wherein a portion of the battery cover is in contact with the cross member.

11 . The vehicle body rear structure of claim 10 ,

wherein the rear module mounting panel further includes a bent portion connecting the mounting portion and the module connection portion, and

wherein the bent portion supports the battery cover.
