Abstract: A side diffuser for a vehicle front surface structure, the vehicle front surface structure, and a method for assembling such a structure. The side diffuser guides air entering through air inlets from bumpers of the vehicle to heat exchangers located in front of the engine. The diffuser includes a plate, the back edge of which supports the heat exchangers and the front edge of which supports the bumpers and includes a recess capable of receiving the front crosspiece end of the vehicle. The back side of the diffuser includes: a pivoting axis capable of engaging with a corresponding receiving part provided on the heat exchangers, and an attaching part capable of engaging with a corresponding attaching part provided on the heat exchangers after one rotation of the side diffuser around pivoting axis.

Abstract: An automobile body for receiving a bumper-forming member and including: a front crossbar; a pair of bearings for the bumper-forming member; and an air intake duct into the engine, the duct including an open end through which the outside air enters the duct. One of the bearings includes a protection portion of the open end, wherein the protection portion is provided in close proximity to the open end, covers the open end, and extends along a portion of the duct, while a gap is provided between the protection portion and the duct so that the air can flow into the duct through the open end.
