2. Description of the Related Art FIG. 3 shows a conventional structure, in which 1 is a door body, 4 is a door weather strip attached to the peripheral wall 2 of the door body 1, and this door weather strip 4 is attached to the opening edge of the vehicle body. In the case of No. 3, the seal lip 5 has a hollow seal lip 5 that is in close contact with the side sill 11, and a base portion 6 that is attached to the two surfaces of the peripheral wall. The base part 6 is formed with a hollow part 7 for accommodating the clip head, and the clip 8 is attached to the base part 6 by passing through the clip head 8a and inserting it into the hollow part 7 and engaging it. The door weather strip 4 is attached to the peripheral wall 2 of the door body 1 by press-fitting and engaging the clip 8 into a clip hole 3 formed in the peripheral wall 2. This similar structure is shown in, for example, Japanese Utility Model Application Publication No. 55-36034.

[Problems to be Solved by the Invention] A water drain hole 9 which also serves as a paint drain is formed in the bottom of the peripheral wall 2 of the door body 1 near the hemming part 1a, so that water can be drained from the door waist opening into the door body 1. If water enters the vehicle, it can be drained out of the vehicle through this drain hole 9. However, this drain hole 9
Since the is located in a narrow location, if the water is clogged, or if there is a large amount of water entering the door body 1 even if it is not clogged, water will accumulate at the bottom of the door body 1. The water may leak out from the clip hole 3 to the interior of the vehicle as shown by arrow a in FIG. If water leaks into the passenger compartment from the clip hole 3 in this way, the water may splash over the side sill 11 into the passenger compartment or flow into the hollow part of the seal lip 5 through the air vent hole 10 of the seal lip 5. As a result, the water that has flowed into the seal lip 5 when the door is closed may scatter into the passenger compartment from the air vent hole 10, and furthermore, the water that has flowed into the seal lip 5 when the door is closed may be scattered into the passenger compartment through the air vent hole 10. This causes problems such as water freezing.

SUMMARY OF THE INVENTION Accordingly, the present invention provides a water drainage structure for an automobile door that can prevent water that has entered the door body from leaking into the vehicle interior through a clip hole at the bottom of the peripheral wall.

[0005]

[Means for Solving the Problems] A clip hole is formed in the peripheral wall of the door body, and a hollow part for accommodating the clip head is formed in the base part of the door weather strip, and the clip is inserted through the base part. A clip disposed at the bottom of the peripheral wall of the door body, in a structure in which the head is inserted and engaged in the hollow part, and the clip is press-fitted and engaged in the clip hole to attach the door weather strip to the peripheral wall of the door body. A communication path is formed to connect the interior of the door body and a hollow portion of the base portion of the door weather strip, and a drain hole that opens to the outside of the vehicle is formed in the hollow portion.

[0006]

[Operation] When water enters and stays inside the door body, this water flows out into the hollow part of the base of the door weather strip through the communication path of the clip, and from the hollow part through the water drain hole. Water is drained outside the vehicle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, with the same reference numerals assigned to the same parts as in the conventional structure.

In FIG. 1, a clip hole 3 is formed in the peripheral wall 2 of the door body 1, and a hollow part 7 for accommodating the clip head is formed in the base part 6 of the door weather strip 4. , the head part 8a of the clip 8 is inserted into the hollow part 7 by penetrating this base part 6, and is engaged, and the clip 8 is sub-assembled to the base part 6; The basic structure is the same as that of the prior art, such as the fact that the clip 8 is press-fitted into the clip hole 3 and attached to the peripheral wall 2 of the door body 1.

Here, a communication passage 12 is formed in the clip 8 disposed at the bottom of the peripheral wall 2 of the door body 1 to communicate the inside of the door body 1 and the hollow part 7 of the base part 6 of the door weather strip 4. In addition, a water drain hole 13 is formed in the hollow portion 7 and opens to the outside of the vehicle.

In this embodiment, a communication passage 12 is formed in the center of the clip 8 by penetrating from the clip head 8a into an open hollow locking part at the tip of the clip. is formed by penetrating the side wall of the hollow portion 7 on the outside of the vehicle.

Therefore, according to the structure of this embodiment, even if water enters the door body 1 and accumulates at the bottom of the door body 1, this water will flow from the communication path 12 of the clip 8 to the door. The water flows into the hollow part 7 of the base part 6 of the weather strip 4, and is smoothly drained from the hollow part 7 through the water drain hole 13 to the outside of the vehicle as shown by arrow b in FIG. Water will not accumulate at the bottom of the
Therefore, it is possible to prevent water from leaking into the passenger compartment from the fitting portion between the clip hole 3 and the clip 8 at the bottom of the peripheral wall 2.

In the embodiment described above, the drain hole 13 is provided through the side wall of the hollow portion 7 on the outside of the vehicle, but in some cases, as shown in FIG. A water drain hole 13 is formed by penetrating the partition wall that separates the hollow part 7 and the side wall of the seal lip 5 on the outside of the vehicle, and drains water from the hollow part 7 through the inside of the seal lip 5 to the outside of the vehicle. You can do it like this.

[0013]

As described above, according to the present invention, water that enters the door body and collects at the inner bottom of the door body can be absorbed through the communication path formed in the clip and the hollow part of the base of the door weather strip. Water can be drained out of the vehicle from the water drain hole formed in the hollow part, so water does not accumulate at the bottom of the door body, and water does not accumulate at the bottom of the door body. This has the advantage of preventing water from leaking into the interior of the vehicle, significantly improving quality and reliability.
