れている。BACKGROUND OF THE INVENTION As a conventional water leak prevention structure for a back door, those shown in FIGS. 1 to 3 are known. In other words, the water leakage prevention structure includes a bank door glass 5 which is attached to the upper edge 3a of a rear opening 3 formed in a body panel 2 at the rear of the vehicle 1 so as to be openable and closable via a hinge member 4. A water droplet dam part 6 is integrally formed around the upper peripheral edge 5aKG to prevent water droplets adhering to the back door glass 5 from flowing into the vehicle interior R, and the water droplet dam part 5 has a tip. 7a forms a bridge portion 7 fixed to the vehicle body panel 2 side, and on the bridge portion 7, when the bank door glass 5 is opened (see Fig. 5), water drops are collected in the dam portion 6. It is constructed by forming a water guide groove 9 for guiding water droplets to a drainage passage 8 provided on the vehicle body panel 2 side.

The rain gutter portions 7b and 7c forming the water guide groove 9 are formed in an upright manner. Moreover, on the opposite side from the bridge part 7,
A tongue portion 10 is formed to be joined to the back door glass 5. Further, both ends of the hinge member 40, which is pivotally supported around the pivot shaft 11, are fixed to the vehicle body nozzle 2 and the back door glass 5 side, respectively, with fasteners 12 and 13. In FIG. 4, 14.14 is a screw hole into which the set screw 12a forming the stopper 12 is inserted, and 15.15 is a screw hole into which the set screw 13a forming the stopper 13 is inserted. This is a pin hole to be inserted.

ドアガラス５の開放時に水滴が車室内Ｒに流入するのを
防止できる。By the way, according to the conventional water leakage prevention structure of the back door having a similar configuration, when the bank door glass 5 is opened, the water droplets adhering to the glass 5 are once drained to the water droplet dam part 6 side. The water droplets collect in the water, are guided from the dam part 6 to the water guide groove 9, and after passing through the water guide groove 9, fall onto the drainage passage 8 provided on the vehicle body panel 2 side, so that the back door glass 5 It is possible to prevent water droplets from flowing into the vehicle interior R when the vehicle is opened.

あった。However, in the water leak prevention structure of the back door having such a configuration, the bridge portion 7 and the water droplet dam portion 6 are formed separately, and the bridge portion 7 and the water droplet dam portion 6 are formed separately.
Since the water droplet dam part 6 and the bridge part 7 may be separated during long-term use, the water droplets accumulated on the water droplet dam part 6 side may be attached to the bridge part. Water droplets are no longer guided into the water guide groove 9 formed on the water guide groove 7, and therefore, water droplets sometimes flow into the vehicle interior R. In addition, there is a drawback in that the water droplet dam part 6 and the bridge part 7 must be formed and bonded together.

体形成されている。As shown in FIGS. 6 to 8, a back door glass 5 can be opened and closed via a hinge member 4 to an upper edge 3a of a rear opening 3 formed in a rear body panel 2 of the vehicle 1. A clamping portion 16 is integrally formed on the upper peripheral edge 5a of the back door glass 5, along with the upper edge 5aKa. Further, a water droplet dam part 6 is integrally formed in this clamping part 16 to prevent water droplets adhering to the bank door glass 5 from flowing into the vehicle interior R (Fig. 8). reference). This water droplet dam part 6 has a tip 7.
A is formed with a bridge portion 7 fixed to the side of the vehicle body panel 2. Therefore, the vehicle body panel 2 and the back door glass 5 are connected to each other at this bridge portion 7. These sandwiching portions 16 , the bridge portion 7 and the water droplet dam portion 6 are integrally formed with the door glass 5 from a thermoplastic resin such as Nucleol resin, which has high clamping strength and high mechanical strength.

It can be integrally joined to the door glass 5 with mechanical strength. Therefore, the clamping part 16 and the water droplet dam part 6 can be integrally bonded to the back door glass 5 without using a conventional fastener. In addition, since the water droplet dam part 6 and the bridge part 7 are integrally molded with nuclear resin, the water droplet dam part 6 and the bridge part 7 can be integrated with mechanical strength, so that when the bank door glass 5 is opened and closed, In such cases, they will not separate. Therefore, water droplets can be prevented from inadvertently flowing into the vehicle interior R.
