BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body structure in which a weather strip is attached to an opening formed in a vehicle body.

[0002]

2. Description of the Related Art For example, in an automobile having an opening such as a tailgate or a trunk room in a vehicle body, a conventional vehicle is disclosed in US Pat.
As shown in Japanese Patent No. 91741, a mounting flange is protruded from a periphery of the opening to fit a weather strip having a seal lip in contact with a vehicle body to the mounting flange, while the opening in the vehicle body is provided. A bumper is provided along the lower edge, and the bumper is bolted to the vehicle body.

In the above-described automobile, for example, when high-pressure water directly hits the seal lip of the weather strip at the time of washing, the seal lip floats up from the vehicle body due to water pressure, and water passes through the seal lip, and the water passes through the seal lip. There is a risk of intrusion into the vehicle interior through a gap between the fitting groove and the mounting flange.

In view of the above-mentioned problems, conventionally, as shown in Japanese Utility Model Application Laid-Open No. Sho 61-42358, the seal lip is pressed toward the vehicle body by the upper end of a bumper disposed below the opening. In order to prevent the sealing lip from floating, there has been proposed a sealing lip.

Flows down between the mounting flange located at the position (1) and the fitting groove of the weather strip fitted to the mounting flange. Therefore, when the seal lip is pressed against the vehicle body via the bumper as described above, it is difficult to discharge the rainwater to the outside.

To solve the above problem, it is conceivable to partially cut out the seal lip and discharge the rainwater from the cutout to the outside. However, with the above structure, the rainwater is discharged from the cutout. Water flows down the surface of the bumper, and the surface of the bumper becomes dirty.

The present invention has been developed in view of the above-mentioned circumstances, and an object thereof is, for example, when a car is washed with high-pressure water, the floating of the seal lip can be surely prevented, and the bumper of the bumper can be prevented. An object of the present invention is to provide a vehicle body structure capable of discharging water entering between the opening edge and the fitting groove of the weather strip fitted to the opening edge without soiling the surface.
