DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention, as shown in FIGS. 1 to 4, includes a weathering 18 formed between a lower end portion 13 of a door 12 of an automobile 10 and a rocker 16 extending in the front-rear direction of the vehicle body. It is a structure that is closed by the strip 20.

At the lower end of the door 12, there is provided a hole 15 for draining water that enters the interior of the door 12 from the belt line 14 of the door 12, that is, the portion where the window glass of the door enters and exits with respect to the outer panel. Multiple holes 1
5 are preferably arranged at intervals in the front-rear direction of the vehicle body, and in the embodiment shown in FIG. 5, five holes 15 are provided.

A weather strip 22 is arranged between the door 12 and the rocker 16 to shut off the inside and the outside of the automobile. The weather strip 22 has a clearance 1 for muddy water.
There is no effect of preventing the adherence to the upper outer side surface 17 of the rocker 16 by entering from the 8 side. Therefore, the weather strip 20
Is attached to the door 12 so as to close the clearance 18.

As shown in FIG. 1, the weather strip 20 comprises a support portion 24 and a lip portion 25, which are integrally formed by extruding rubber. Hole 1 in the door 12
The support portion 24 is provided with a recess 26 that extends in the front-rear direction of the vehicle body for receiving the water falling from the vehicle 5. Weather strip 20
Is a predetermined length L1 in the longitudinal direction of the vehicle body as shown in FIG.
However, by providing the concave portion 26 over the length L1 of the weather strip 20, the water guided to the concave portion 26 can be formed by the front end 2 of the weather strip 20.
7 or can be discharged from the rear end 28.

The original weather strip 22 attached to the inner surface of the door 12 has the cross-sectional shape shown in FIG. 2 and, as shown in FIG. 4, passes from the front end 30 to the lower end 13 of the inner surface of the door 12. Although the rear end portion 31 is arranged in a substantially semi-elliptical shape, the length L1 of the weather strip 20 can be determined in consideration of the following circumstances.

When the occupant gets on and off, it is considered that the skirt of the clothes touches the upper outer surface 17 of the rocker 16 within the range shown by hatching in FIG. That is, normally, the distance L2 is behind the opening position of the door and is the range L3 in front of the hinge 35 of the seat 34, but in consideration of the size of the extension, the distance L2 is in the front and the distance between the hinges 35 is in the rear. It is sufficient to set L4 as the range (L2 + L3 + L4). By arranging the weather strip 20 in this range, it is possible to prevent the clothes from being soiled by the rocker 16 of the garment while maintaining economy.

When the weather strip 20 is set in the above range, its length L1 becomes substantially the same as the straight line portion of the weather strip 22. Therefore, the weather strip 2
As shown in FIG. 1, even when 0 is abutted against the weather strip 22 and attached to the door 12, the weather strip 20 can be kept horizontal, and the water in the recess 26 can easily flow.

The weather strip 22 is attached to the door 12 by inserting the clip 40 into the hole provided in the door 12, but the weather strip 20 can be attached in the same manner. In addition to this installation, the door 1 when opening the door 12
To ensure a sense of unity between the 2 and the weather strip 20,
Door hemming flange 42 and weather strip 20
It is preferable to dispose an adhesive such as a double-sided tape or butyl between the supporting part 24 and the supporting part 24 to adhere them. this is,
It is particularly suitable when the weather strip 20 is a so-called optional attachment.

As another measure for ensuring a sense of unity between the door and the weather strip, the one shown in FIGS. 6 and 7 can be adopted. In this embodiment, the hemming flange portion 44 of the door 12 is slightly separated toward the inside of the vehicle body, while the weather strip 4 having the support portion 47 and the lip portion 48 is provided.
A recess 49 is provided in the support portion 47 of No. 6, the hemming flange portion 44 is fitted in the recess 49, and the weather strip 46 is brought into close contact with the door 12. In this case, the opening dimension a of the recess 49 is determined to be smaller than the effective length b of the hemming flange portion 44, as shown in FIG. The recess 26 for receiving the water falling from the hole of the door 12 has the same structure as the above-mentioned embodiment.

When the weather strips 20 and 46 are attached to the door 12, the lip portions 25 and 48 are in close contact with the outer surface of the rocker 16 to prevent muddy water or the like from adhering to the upper outer surface 17 of the rocker.

In the above embodiment, the weather strip 20,
The hatched support portions 24 and 47 of 46 are solid rubber, and the lip portions 25 and 48 are sponge rubber. By doing so, the support rigidity of the weather strip becomes high, the assembly becomes easy, and the adhesion at the time of assembly becomes high. However, it is also possible to mold it entirely with solid rubber or with sponge rubber.

As in the above embodiment, the weather strip 2
By bringing the lip portions 25 and 48 of 0 and 46 into close contact with the outer surface of the rocker 16, the following effects can be obtained. That is, for example, in a special situation where the window glass is slightly lowered to operate the cooler, a negative pressure may be generated in the passenger compartment, and thus dust from the outside may be sucked through the hole 15 of the door. The lip portions 25 and 48 can prevent such a phenomenon from occurring.
