Description

  The present invention relates to a rear structure of a vehicle body that prevents intrusion of scattered rainwater.

Some automobiles have a mechanism for preventing the intrusion of scattered objects because rainwater and mud may be scattered backwards during traveling (see, for example, Patent Document 1).
Japanese Patent Publication No. 1-15410 (3rd page, Fig. 2)

Patent document 1 is demonstrated based on the following figure.
FIG. 10 is a diagram for explaining the basic configuration of the conventional technique. The conventional engine intake air intake structure is configured such that a flexible shielding plate 203 is hung from the rear end portion 202 of the vehicle body 201 so that the rear end The gap between the portion 202 and the lower part of the bumper 204 can be blocked, and mud and water can be prevented from entering.

However, in the engine intake air intake structure of Patent Document 1, when the shielding plate 203 is suspended from the rear end portion 202 and brought into contact with the lower portion of the bumper 204, the shielding plate 203 comes out from under the bumper 204 and is visible. Therefore, the appearance of the rear part of the vehicle is deteriorated.
Also, when mud or water pushes the shield plate 203 vigorously, especially when passing through a deep water pool, the amount of water blown backward along the bottom of the vehicle by the front wheels is large and the pressure becomes high, The flexible shielding plate 203 may be bent too much and enter the bumper 204.

  The present invention improves the appearance of the rear part of the vehicle, prevents the scattered rainwater guard seal member from entering the rear bumper, facilitates the assembly of the rear bumper, and shortens the length of the scattered rainwater guard seal member in the vehicle width direction. It is an object to provide a rear structure.

  In the invention according to claim 1, a scattered rainwater guard seal member for preventing the intrusion of water and mud scattered between the rear bumper and the rear end panel of the vehicle body is arranged away from the rear bumper, and is in close contact with the rear bumper by pressing the scattered rainwater. In the rear structure of the vehicle body that prevents intrusion, the scattered rainwater guard seal member is a long seal main body that closely adheres to the upper lower surface of the rear bumper, and is orthogonal to the seal main body, and the seal main body presses the upper lower surface. And a stopper rib that sometimes contacts the rear end panel.

  In the rear structure of the vehicle body, the scattered rainwater guard seal member has a long seal body that closely follows the upper and lower surfaces of the rear bumper, so that when the vehicle travels in the rain, the rainwater scattered on the front wheels When the scattered rainwater guard seal member is reached, the scattered rainwater guard seal member is elastically deformed, and the seal body is pressed against the upper lower surface of the rear bumper and comes into close contact therewith. As a result, the scattered rainwater guard seal member can prevent rainwater from entering between the upper portion of the rear bumper and the rear end panel.

  The invention according to claim 2 is characterized in that it includes end wall portions that are formed at both ends of the scattered rainwater guard seal member and guide the scattered matter reaching both ends downward.

  In the invention according to claim 1, the scattered rainwater guard seal member is disposed away from the rear bumper and includes a long seal body portion that closely adheres to the upper lower surface of the rear bumper. The appearance of the rear part of the vehicle can be improved without leaving the lower part and without impairing the prevention of rainwater intrusion.

  Further, since the scattered rainwater guard seal member is provided with a stopper rib that is orthogonal to the seal body portion and abuts against the rear end panel when the seal body portion presses the upper lower surface, the elastic deformation amount of the seal body portion is reduced by the stopper rib. Determined. Therefore, it is possible to prevent the scattered rainwater guard seal member from entering the rear bumper.

  In addition, the scattered rainwater guard seal member has a long seal body portion that closely follows the upper lower surface of the rear bumper, and is arranged at a position away from the rear bumper. Attaching becomes easy.

  In the invention which concerns on Claim 2, it was formed in the both ends of the scattered rainwater guard seal member, and since it was provided with the termination | terminus wall part which guides the scattered material which reached both ends below, a part of rainwater which reached the scattered rainwater guard seal member When it flows to both ends, it is guided down by the end wall and falls.
