BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a front fender in a vehicle.

[0002]

2. Description of the Related Art As this kind of waterproof structure, for example, one disclosed in Japanese Patent Application Laid-Open No. 3-31074 is known.

In such a waterproof structure, a front part of a protector formed in an arc shape along the shape of the opening of the front fender is superimposed on the upper surface of a lower edge flange at the front of the opening of the front fender. A weir is formed at the front side to prevent the flow of mud flowing toward the front of the bumper along the upper surface of the protector. The mud is splashed up by the front tires and enters the upper surface of the protector. If the mud flows out in front of the bumper, the appearance of the vehicle body is impaired.

[0004]

By the way, the muddy water splashed up by the front tire sometimes enters not only the upper surface of the protector but also between the front fender and the protector.

However, in the above-mentioned conventional waterproof structure, the flow of muddy water that has entered between the front fender and the protector cannot be prevented, and the muddy water is transmitted to the front of the bumper, and the appearance of the vehicle body is reduced. There was a problem that would impair.

An object of the present invention is to prevent not only the flow of the muddy water flowing along the upper surface of the protector but also the flow of the muddy water flowing out of the front fender and the protector toward the front of the bumper. Another object of the present invention is to provide a waterproof structure for a front fender that can reliably avoid loss of aesthetics of a vehicle body due to outflow of muddy water.

[0007]

The waterproof structure of the front fender according to the present invention is such that the front part of the protector is overlapped on the upper surface of the lower edge flange formed at the front part of the opening of the front fender, and A wall portion is formed on the upper surface of the portion, extending substantially along the width direction of the lower edge flange, to prevent a flow of muddy water flowing out to the front side along the upper surface of the protector. The flow of muddy water which is elastically pressed against the upper surface of the lower edge flange portion along the substantially width direction of the lower edge flange to pass through the space between the front fender and the protector and flows to the front side. Characterized in that an elastic piece is formed to prevent the occurrence of the pressure.

[0008]

According to the present invention, the waterproof structure of the front fender has elasticity at the front portion of the protector which overlaps the upper surface of the lower edge flange of the front fender, the wall portion located on the upper surface, and the upper surface of the lower edge flange of the front fender. With the elastic piece pressed against the protector, the wall prevents the flow of the muddy water flowing out along the upper surface of the protector, and the elastic piece prevents the muddy water from flowing between the front fender and the protector. The flow of the invading mud is prevented, and the loss of the appearance of the vehicle body due to the outflow of the mud in front of the bumper is reliably prevented.

[0009] The elastic piece formed on the protector is
Irrespective of the variation in assembling the front fender and the protector, it is pressed against the upper surface of the lower edge flange of the front fender to reliably prevent the flow of muddy water.
