Here, when a large / large diameter tire is mounted on a vehicle such as an SUV, the width dimension of the decorative member provided around the wheel house may be increased in consideration of the design of the entire vehicle. However, when the door is adjacent to the wheel house (rear door in the case of so-called 4-door), if a wide decorative member is attached to the vehicle body along the outer edge of the wheel house, the opening area of the door becomes small. Therefore, in order to secure the opening area of the door, it is necessary to attach a part of such a decorative member to the door.

In addition, since the deflector for the rear tire must be installed on the front side of the vehicle of the rear tire, it must be installed below the door (rear door), and when a large rear tire is installed, its rectifying performance is exhibited. , The deflector also needs to be large.

However, in such a case, if a deflector is attached to the decorative member of the door, the deflector may come into contact with a curb on the road surface when the door is opened or closed. On the other hand, there is also a method of fixing the deflector to the lower surface of the side sill, but in this case, when trying to increase the size of the deflector, there is a problem that the support rigidity cannot be sufficiently secured and only a small deflector can be provided. rice field.

Therefore, the present invention has been made to solve the above-mentioned problems, and secures the opening area of the door while improving the design of the vehicle, and secures the support rigidity of the deflector to improve the aerodynamic performance. It is an object of the present invention to provide a side body structure of a vehicle that can be made to.

In order to solve the above-mentioned problems, the present invention relates to a wheel house formed on the side of the vehicle body and accommodating tires, a door for opening and closing an opening formed on the side of the vehicle body, and a side portion of the vehicle body. It is a side body structure of a vehicle that is formed and includes a side sill that extends below the door in the front-rear direction of the vehicle, and the door is provided with a decorative member that covers an arch portion that extends along the wheel house. A cover member that covers at least the side surface is fixed to the side sill, and a rear extension that is integrally formed with the cover member between the door decoration member and the vehicle body in the vehicle vehicle width direction is fixed to the side portion of the vehicle body. It is characterized in that a protrusion is provided and a deflector is fixed to the rear extension.

According to the present invention configured in this way, the door is provided with a decorative member (so-called arch molding, garnish, etc.) that covers the arch portion extending along the wheel house, and the side sill of the vehicle body has at least a side surface thereof. A cover member (so-called side step molding, etc.) is fixed to cover the vehicle, and a rear extension is integrally formed with the cover member between the door decoration member in the vehicle width direction and the vehicle body on the side of the vehicle body. A protrusion is provided, and a deflector is fixed to this rear extension. Therefore, by providing the decorative member on the door, the design of the vehicle is improved while securing the opening area of the door, and the rear extension is integrally formed with the cover member fixed to the side sill with high mounting rigidity. By fixing the deflector to the protrusion, the support rigidity of the deflector can be secured and the aerodynamic performance can be improved.

Further, in the present invention, preferably, the rear extending portion of the cover member is fixed to the side panel of the vehicle body.
According to the present invention configured as described above, the support rigidity of the deflector can be ensured more reliably.

Further, in the present invention, preferably, a seal member for closing the gap with the door is provided on the side surface of the cover member, and the seal member is provided on the rear extending portion of the cover member and the side of the wheel house on the door side. It is provided so as to extend integrally over the portions.
According to the present invention configured as described above, the sealing member (so-called weather strip) for closing the gap with the door is provided on the rear extending portion of the cover member (for example, the side step molding) and the door side of the wheel house. Since it is provided so as to extend integrally over the portions, it is possible to effectively prevent the intrusion of water from the outside of the vehicle.

Further, in the present invention, preferably, the rear extending portion of the cover member is configured to form a closed cross section with the side panel of the vehicle body.
According to the present invention configured as described above, since the rear extending portion forms a closed cross section with the side panel of the vehicle body, the rigidity of the rear extending portion can be increased, whereby when the door is opened. When the occupant comes into contact with the rear extension portion when the occupant gets into the passenger compartment, the deformation of the rear extension portion can be prevented.

According to the side body structure of the vehicle of the present invention, it is possible to improve the design of the vehicle while securing the opening area of the door, and to secure the support rigidity of the deflector to improve the aerodynamic performance.
