３固定していた。 For example, as shown in FIG. 1, there is an automobile back door 1 in which the upper part of the back door 1 is formed of back door glass 2 and the lower part is formed of a back door panel 3a made of a steel plate (Nissan Sunny B11 model car).
However, in order to improve the loadability of luggage, etc., the second
As shown in the figure, a structure has been considered in which the center portion of the back door panel 3 extends above the bumper 24.
In this case, the back door panel 3 is formed into a closed section structure by an outer panel 4 and an inner panel 5 whose peripheral edges are hemmed, as shown in FIGS. 3 and 4. The inner panel 5 is formed to bulge on the back side of the hanging portion 6 provided, and the lower end surface 9 of the back door glass 2 is aligned on the upper end surface 8 of this bulge portion 7, and the bulge is formed at the joint portion 10. After adjusting the thickness of the spacer bar 11 so that the part 7 and the back door glass 2 are connected on the same plane, attach the back door glass 2 and the spacer bar 11 to the back door panel 3 with bolts 2.
3 was fixed.

している。 On the other hand, the back door opening of the vehicle body is opened in substantially the same shape as the back door 1, and as shown in FIGS. 2 to 4, a weather strip 12 as a sealing member attached to the periphery of the opening The periphery of the back side of 1 was elastically sealed to maintain watertightness in the passenger compartment. Note that 12A indicates a portion where the weather strip 12 comes into contact with the backdoor 1.
ところで、このようなタイプのシール構造で

つた問題があつた。 By the way, in this type of seal structure, since the weather strip 12 goes around to the hanging part 6 of the back door panel 3, the joint part 10 between the back door glass 2 and the bulging part 7 of the back door panel 3 is The weather strip 12 will be sealed in a straddling state. As a result, for example,
As shown in FIGS. 3 and 4, when a gap 13 is created in the joint 10 due to an installation error between the back door glass 2 and the back door panel 3, a molding error in the back door panel 3, etc. Since the weather strip 12 cannot close the gap 13, the inside of the vehicle and the outside of the vehicle are communicated through the gap 13. Therefore, when the joint 10 is directly hit by water spray during a car wash or the like, there is a problem in that the water flows into the gap 13, passes over the weather strip 12, and enters the passenger compartment.

とにある。 The gist of the present invention is a back door sealing structure in which a back door glass is directly applied to the peripheral edge of a back door opening opened at the rear of a vehicle body for sealing, and a back door panel is attached to the bottom surface of the back door glass. The back door glass is reinforced by overlapping and joining the two, and a hanging part is provided at the center of the lower end of the back door panel, and this hanging part opens the back door opening cut out along the rear combination lamp. While closing the lower extension part, a bulge is formed inside the hanging part, and the upper edge of the bulge and the lower edge of the back door glass are aligned so as to touch each other to close the back door. The inner surface of the glass and the surface of the bulge are connected on the same plane, and when the back door is closed, the periphery of the back door glass and the periphery of the bulge are brought into elastic contact with a sealing member attached to the periphery of the back door opening. In the sealing structure of the back door that seals the aligned joint, the back door has a sealing structure in the vicinity of the joint,
Further, a vertical wall-shaped water-shielding portion facing toward the vehicle body is provided on the outside of the sealing member, and the water-shielding portion shields the joint portion from the outside when the back door is closed.
以下添付図面に示す実施例に基づいて本発明を

リツプ１９の止着孔２１が開設されている。 In one embodiment of the present invention shown in FIGS. 5 to 9, a back door panel 3 and a back door glass 2 are provided.
A spacer bar 14 interposed between the back door panel 3 and the back door panel 3 is formed to have substantially the same shape as the back door panel 3, and has a lower end face 9 of the back door glass 2 and a bulge 7 of the back door panel 3 on both sides of its lower end. A pair of vertical wall-shaped water shielding portions 15 are provided to shield the joint portion 10 formed between the upper end surface 8 and the upper end surface 8 of the water shielding portion 10 .
The water-blocking portion 15 includes a horizontal wall 16 bent from the lower end of the spacer rubber 14 toward the inside of the vehicle;
It is composed of a vertical wall 17 bent downward from the inner end of the horizontal wall 16, and a mounting wall 18 whose surface perpendicular to the vertical wall 17 is on the same plane as the general surface of the spacer rubber 14. , said mounting wall 1
8 is provided with an insertion hole 20 for fixing the clip 19 to the back door panel 3. Incidentally, fixing holes 21 for the clips 19 are provided on both sides of the general surface of the bulging portion 7 of the inner panel 5 of the back door panel 3 at positions corresponding to the above-mentioned insertion holes 20.

３をこれによつて埋めることができる。 Further, in the above embodiment, the second horizontal wall 22 sandwiched between the left and right mounting walls 18, 18 is connected to the spacer bar 14.
This second horizontal wall 22 is formed on the same plane as the horizontal wall 16 of the water-blocking part 15, and the gap 1 formed in the joint part 10 is
3 can be filled in with this.

位置は従来と同様、膨出部７の両端部である。 The spacer bar 14 having the above structure has a mounting wall 18 fixed to the back door panel 3 with clips 19, and is also attached together with the back door glass 2 while being sandwiched between the back door panel 3 and the back door glass 2. They are fastened together with bolts 23. The spacer bar 14 interposed between the back door panel 3 and the back door glass 2 in this way covers the lower end surface 9 of the back door glass 2 with the horizontal wall 16 of the water shielding part 15, and also covers the lower end surface 9 of the back door glass 2 with the vertical wall 17. Since both sides of the bulging portion 7 are covered and hidden, the joint 10 between the back door panel 3 and the back door glass 2 is completely shielded from the outside. Further, in the joint portion 10, a second horizontal wall 2 is provided in the gap 13.
2 is stuck. Incidentally, the positions where the weather strip 12 as a sealing member straddles the joint portion 10 are at both ends of the bulge portion 7, as in the conventional case.
従つて、洗車時に上記接合部１０近傍を放水で
直撃した場合に、遮水部１５の水平壁１６と垂直

合部１０に形成される隙間１３を第２の水平壁２
２で塞いでいるため、更に遮水効果がよくなり、
接合部１０を通じて車室内に水が浸入するといつ
たことを確実に防止することができる。 Therefore, when the vicinity of the joint 10 is directly hit by water spray during car washing, the horizontal wall 16 and the vertical wall 17 of the water shielding part 15 completely prevent the water from entering the joint 10. Since water flows to the outside along the vertical wall 17, there is no chance of water entering the joint 10. Further, in this embodiment, the gap 13 formed in the joint 10 is replaced by the second horizontal wall 2.
2, the water shielding effect is even better,
It is possible to reliably prevent water from entering the vehicle interior through the joint 10.
尚、上記実施例では遮水部１５の水平壁１６が
サポートラバー１４の両側部まで延びている例に
ついて説明したが、この水平壁１６は少なくとも
垂直壁１７との接続部近傍部分にだけ形成されて
いれば、接合部１０の遮水効果を十分に持ち得
る。 In the above embodiment, the horizontal wall 16 of the water shielding part 15 extends to both sides of the support rubber 14, but the horizontal wall 16 is formed only at least in the vicinity of the connection with the vertical wall 17. If it is, the joint portion 10 can have a sufficient water-shielding effect.
以上説明したように本発明に係るバツクドアの

できた。 As explained above, according to the sealing structure of the backdoor according to the present invention, the joint between the backdoor glass and the backdoor panel is shielded from the outside, so even if the joint is directly hit by water, There were no cases of water infiltrating the joints, and we were able to further improve the watertightness of the interior of the vehicle.
