In addition, the bolts 10 etc. are exposed, which makes it unattractive.
In addition, when the opening 4a of the cowl cover 4 is blocked by snow or the like, the amount of outside air introduced decreases, and the ventilation performance in the vehicle compartment deteriorates.

Therefore, the present invention has an object to suppress the inflow of water to the engine room side, improve the degree of freedom in molding, ensure the appearance quality, and allow the outside air to be introduced well. ing.

[Means for Solving the Problems] The present invention has been made in view of the above-mentioned conventional problems, and an air box is formed below the lower edge of the front window panel along the vehicle width direction. An outside air introduction port for introducing outside air is formed on the box side upper surface of the box, and a cowl cover having an opening communicating with the outside air introduction port is placed on the box side upper surface.
Both ends of the box-side upper surface part are placed on the side-side upper surface part of the cowl top side that closes both ends of the air box, and a hood hinge is fixed to the side-side upper surface part. In the side portion structure, an embossed portion is formed at a hood hinge attachment portion of the side-side upper surface portion, both end portions of the cowl cover are extended, and the extended portion is set to cover the embossed portion,
A first space portion that is open to the outside of the vehicle is formed between the embossed portion and the cowl cover, and a concave portion that extends from the embossed portion to the outside air introduction port is formed in the box-side upper surface portion to form the concave portion and the cowl cover. In between, a second space portion that is continuous with the first space portion and reaches the outside air introduction port is formed, and an outside air introduction path that extends from the outside of the vehicle to the outside air introduction port is formed in the first and second space portions. It is characterized by the side structure of the air box for automobiles.

[Operation] According to this means, when the opening of the cowl cover is covered with snow, the outside air is introduced from the outside air introduction port of the air box side upper surface portion through the outside air introduction passage, and therefore, compared to the conventional case. Ventilation performance is improved.

Further, the water that has entered between the cowl cover and the upper surface of the air box flows over the concave portion of the second space portion, travels over the embossed portion of the first space portion, and is discharged outside the vehicle. Therefore, the flow of water to the engine room side is suppressed, and adverse effects on electrical components and the like are suppressed.

Further, by forming the embossed portion at the hood hinge attachment portion, the position of the hood hinge can be set lower, so that the hood can be positioned lower than in the past, and the degree of freedom in modeling is improved.

Furthermore, since the hood hinge attachment portion and the like are covered by the extension portion of the cowl cover, the appearance quality is improved.

Furthermore, by forming the embossed portion, the strength of the vehicle body is also improved, and it effectively acts on a vehicle light collision, vehicle traveling vibration, and the like.
