An example applied to a side structure of an off-road automobile such as a so-called recreational vehicle is shown, 1 is a door opening provided on a side surface of a vehicle body, 2 is a side sill constituting a lower edge of the door opening 1, 3 Are doors 4 and 5 which are attached to the door opening 1 so as to be openable and closable with the front edge being the hinge side, and reference numerals 4 and 5 are fender portions forming the front and rear vehicle side surfaces of the door opening 1.

The side sill 2 is formed so that its outer side surface 2a in the vehicle width direction is located inward of the outer side surfaces 4a, 5a of the front and rear fender portions 4, 5 by a predetermined amount in the vehicle width direction.

The door 3 is formed by integrally molding a door body 6 and an extending portion 7 extending downward from a lower end portion of the door body 6, and the extending portion 7 includes the side sill. It is formed over the entire length of the door body 6 in the front-rear direction so as to cover the entire outer side surface 2a of the vehicle 2 from the outside in the vehicle width direction. The thickness of the extension 7 and the position where the side sill 2 is formed are such that the door 3 is closed and the outer surface 2a of the side sill 2 is covered by the extension 7.
Outer surface 7a of the front and rear outer surface 4 of the fender portions 4 and 5
It is set so that a and 5a form a continuous surface.

On the outer side surface 7a of the extending portion 7 and the outer side surfaces 4a and 5a of the fender portions 4 and 5, a grooved shaped portion 8 is formed, and the shaped portion 8 faces upward and inclines outward. A slope 8a is formed. In addition, the outer side surface 7 of the extended portion 7
At the lower end portions of a and the outer side surfaces 4a and 5a of the fender portions 4 and 5, a protective coating portion 9 is provided continuously in the front-rear direction of the automobile R. The protective coating portion 9 is formed by coating a normal coating surface with a black protective coating material.

Between the extending portion 7 and the side sill 2,
Two weather strips 10a and 10b are interposed. One weather strip 10a is attached to the extension portion 7,
The other weather strips 10b are attached to the side sills 2, respectively, and prevent water from entering through the gap between the extending portion 7 and the side sills 2.

Next, the operation and effect of the side structure 1 of the above embodiment will be described.
