Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile, and more particularly to an automobile drip structure including a so-called full door in which a door sash portion is integrally press-molded with a door body.

2. Description of the Related Art As shown in FIG.
It is known that a so-called full door, which is formed by press-molding the above with the door body 1, is integrally formed. The door sash part 2 is extended around the door sash upper part 2a around the roof side so that the roof panel 3 and the door sash upper part 2a have a sense of unity to improve the appearance and aerodynamic characteristics. I am trying to In this way, when the door sash upper part 2a is extended around the roof side, the roof drip is divided into the fourth to sixth parts.
The structure shown in the figure is adopted. In the figure, 5 is the vehicle body opening 4.
The roof side rail that constitutes the upper edge of the roof side flange 6 is joined to the outer side surface of the roof side rail. Reference numeral 7 denotes a first drip seal fitted to the roof side flange 6, which comes into close contact with the rear surface of the door sash upper part 2a when the door is closed,
A drip channel section 8 is formed between the upper side portion 2a of the door sash and catches water flowing down from the roof panel 3 and guides it in the longitudinal direction of the vehicle body. 9 is a vehicle body opening 4
A second drip seal 9 is formed at the rear edge of the rear drip seal 9. The second drip seal 9 has a substantially U-shaped cross section and is fixed together with the end of the rear pillar finisher 10. A drip channel section 11 is formed close to the back surface of the section 2b and between the rear side section 2b of the door sash. This similar structure is disclosed, for example, in Japanese Patent Laid-Open No. 5264724/1982.

Problems to be Solved by the Invention Since the first drip seal 7 and the second drip seal 9 are molded separately, at the corner C formed by the upper edge portion and the rear edge portion of the vehicle body opening 4, these If the second drip seals 7 and 9 remain discontinuous as shown in FIG. 4, water leakage will occur at the corner C. Because of this, the first
It is also known that the rear end portion of the drip seal 7 is extended as shown by the chain line in the figure, and the extension portion 7a is curved at the corner C so that the end portion is superposed and continuous inside the second drip seal 9. However, in this case, since the roof side flange 6 does not exist in the corner C, it is necessary to bond the extension portion 7a to the outer surface of the roof side rail 5. For this reason, not only the workability of assembling is deteriorated, but also the adhesive protrudes and is exposed at the corner C on the outer peripheral side of the extension 7a, which impairs the appearance and quality. .

Therefore, the present invention is capable of reliably preventing water leakage at the corner formed by the upper edge portion and the rear edge portion of the vehicle body opening, and further improving the quality and reliability of the automobile drip. It provides the structure.

Means for Solving the Problem One of the claw pieces having substantially the same cross-sectional shape as the roof side flange joined to the outer surface of the roof side rail is attached to the corner formed by the upper edge and the rear edge of the vehicle body opening. A rear end portion of the first drip seal fitted to the roof side flange is extended, an intermediate portion of the extended portion is fitted to the pawl piece and bent downward, and an end portion of the extended portion is formed at the rear edge portion. Is overlapped and connected to the inside of the upper end portion of the second drip seal arranged at.

Action The water, which is captured by the first drip seal and is guided to the rear of the vehicle body, is smoothly guided to the second drip seal side from the extension of the rear end of the first drip seal.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings by attaching the same reference numerals to the same portions as those of the conventional configuration.

In FIGS. 1 and 2, a roof side flange 6 is formed on the outer surface of a roof side rail 5 that constitutes the upper edge of the vehicle body opening 4.
The roof side flange 6 is fitted with the first drip seal 7 and the rear edge of the vehicle body opening 4 is provided with a second drip seal 9.
The basic structure is the same as the above-mentioned conventional one, such as the fact that it is fastened and fixed together with the end of 10.

Here, at a corner portion C formed by the upper edge portion and the rear edge portion of the vehicle body opening 4, a claw piece 15 having substantially the same cross-sectional shape as the roof side flange 6 is attached, while the first drip seal 7 is provided. The rear end portion is extended, the middle of the extension portion 7a is fitted to the claw piece 15 and bent downward, and the end portion of the extension portion 7a is overlapped with the inside of the upper end portion of the second drip seal 9. ， Connected.

As shown in FIG. 2, the overlap and connection between the end of the extension portion 7a of the first drip seal 7 and the inside of the upper end of the second drip seal 9 are performed by connecting the inside of the lip of the upper end of the second drip seal 9 and the rear pillar finisher. The retaining projections 9a and 10a are formed on the edge portions of the respective 10 and the retaining projections 9a and 10a are formed.
Alternatively, the front and rear edges of the extension 7a may be engaged with each other, or the end of the extension 7a may be simply fixed to the inside of the upper end of the second drip seal 9 by adhesion.

In this embodiment, the claw piece 15 extends from the roof panel 3 at the corner C.
It may be joined to the outer surface of the roof side rail 5.

According to the above-described structure of the embodiment, the water flowing down from the surface of the roof panel 3 to the roof side at the time of traveling in the rain is trapped by the drip channel 8 formed by the first drip seal 7 and the door sash upper part 2a. When the water is guided to the rear of the vehicle body by means of the drainage channel 8, the drip channel 8 is extended by the extension 7a of the first drip seal 7 at the corner C formed by the upper edge portion and the rear edge portion of the vehicle body opening 4 to the second edge. Drip channel formed by the drip seal 9 and the rear side part 2b of the door sash
Since it is continuous with No. 11, it is possible to smoothly drain water without causing water leakage at the corner C.

Here, since the extension 7a is fitted and fixed to the claw piece 15 attached to the corner C, the workability of assembling is good, unlike the case where the extension 7a is fixed by an adhesive, and peeling with time occurs. There is nothing to do.

EFFECTS OF THE INVENTION As described above, according to the present invention, the middle of the extension of the rear end of the first drip seal is fitted to the claw piece attached to the corner formed by the upper edge and the rear edge of the vehicle body opening. And then bend downwards, and its end is overlapped and connected to the inside of the upper end of the second drip seal arranged at the rear edge so that the drip channel is continuous at the corner. Therefore, it is possible to reliably prevent water leakage at the corners, and to further improve the quality and reliability. Moreover, since the extension part is fitted and fixed to the claw piece at the corner, the workability of assembling is good, and the extension part is not disengaged from the corner part, so that the quality and reliability are further enhanced. It has a practically great effect of being able to.
