However, since the side part of the cowl box in the engine compartment is a drainage channel for discharging water that has entered the cowl box to the outside of the vehicle, the part where the cowl box meets the front pillar of the left and right body side assemblies is located on the side of the cowl box. It is necessary to create a structure in which the part is superimposed on the waist part of the front pillar to prevent water from entering the cabin side from the side part of the cowl box. For this reason, the left and right body side assemblies are installed in the engine compartment.

In order to assemble it into the intermediate structure consisting of the floor assembly and rear end assembly, the waist part of the front pillar must be superimposed under the side of the cowl box, and the waist part of the front pillar must be attached using the side part of the cowl box as a reference. However, when assembling the left and right body side assemblies based on the side parts of the cowl box, the left and right body side assemblies may be assembled due to variations in dimensions within the manufacturing tolerances of the engine compartment, floor assembly, rear end assembly, and left and right body side assemblies. The alignment between the rear end portion and the side portion of the rear end assembly in the backward direction is likely to deteriorate.

Therefore, the present invention can improve the fit between the rear end portions of the left and right body side assemblies and the side portions of the rear end assembly without impairing the waterproofness of the joint portion between the side portions of the cowl box and the waist portion of the front pillar. It provides body structures for automobiles.
