The rigidity of the undermodule 114 and the rocker portion 116 of the undermodule 114 are improved.

However, in this module assembly structure of an automobile body, an inner flange 120 for connecting the module extends from the upper part of the rocker portion 112 of the upper module 110 inward in the vehicle width direction (left side in FIG. 7), and An outer flange 122 for connecting modules extending from the lower part of the rocker portion 112 of the rocker portion 110 to the outside in the vehicle width direction (right side in FIG. 7) is formed into two panels, each consisting of a rocker upper 124 and a rocker lower 126. Therefore,
The rigidity of these inner flanges 120 and the outer flanges 12
Both the rigidity and the rigidity of 2 are strong and difficult to deform. For this reason, the inner flange 120 of the rocker portion 112 of the upper module 110
and the outer flange 122 together with the undermodule 11
Module coupling portions 116A and 11 of the rocker portion 116 of No. 4
