している。Means for Solving the Problem In order to solve the problem, this invention has a back door main body that opens and closes the opening of the vehicle body, and a glass hatch that opens and closes the main body opening formed in the back door main body, which opens and closes the main body opening. A buffer member is attached to the lower peripheral edge of the main body opening, and a buffer member is attached to the lower peripheral edge of the main body opening to abut against the lower edge of the glass hatch and soften the impact when the glass hatch is closed. In a back door for an automobile, in which a shelf portion whose rear side is inclined diagonally upward is formed in a lower portion of a shock absorbing member, the shock absorbing member is connected to a shock absorbing member main body that abuts the lower edge of the glass hatch, and a downward direction from the shock absorbing member main body. and extends toward the shelf portion, and
The lower end has a height equal to or higher than a substantially horizontal line passing through the top of the shelf, and extends over substantially the entire front and back width of the shelf to block the flow of water on the shelf and to prevent water from flowing below the back door main body. It is characterized by being formed from a dam that leads to the

Through this point, it tries to flow to both sides of the back door body. However, this flow is blocked by the dam formed in the buffer member and guided from there to the bottom of the back door body, so that water does not splash on the seal between the vehicle body and the back door as in the past. Since this seal portion is prevented from accumulating ice, the opening/closing function of the back door body is maintained. Further, since the weir portion is formed in the buffer member, the workability of assembling the back door is ensured without increasing the number of parts.

棚部１４ｄが形成されている。 This backdoor 11 is constructed by having a main body opening 14a formed in a backdoor main body 14, and a glass hatch 15 for opening and closing this opening 14a rotatably attached to the backdoor main body 14. The glass hatch 15 has an upper edge 15a rotatably attached to the back door main body 14 by a hinge (not shown). On the other hand, the main body opening 14
A pair of buffer members 16 are attached to the lower peripheral edge 14b of a, which abut against the lower edge 15b of the glass hatch 15 and provide cushioning when the glass hatch 15 is closed. In addition, in the vicinity of the lower side of the buffer member 16,
As shown in FIGS. 1 and 3, the back door main body 14 is formed with a shelf portion 14d whose rear part is inclined diagonally upward as in the conventional case.

ようになつている。 The buffer member 16 is formed by integrally molding a buffer member main body 17 and a weir portion 18. The buffer member main body 17 has a generally circular shape and is integrally molded with a clip portion 17a, which is attached to a mounting hole 14e formed in the lower peripheral edge portion 14b of the backdoor main body 14 as shown in FIG. By fitting into the buffer member main body 17, the buffer member main body 17 is attached to a position where it comes into contact with the lower end edge 15b of the glass hatch 15. On the other hand, the dam part 18 extends downward from the buffer member main body 17 to the shelf part 14d of the backdoor main body 14. The lower end portion 18a of this weir portion 18 is bent to have a shape that matches the shelf portion 14d, and
The weir portion 18 has a height greater than or equal to a substantially horizontal horizontal line l passing through the top portion 18c of the shelf portion 14d, and extends over substantially the entire longitudinal width W of the shelf portion 14d to block the flow of water on the shelf portion 14d. It is adapted to be guided downward of the back door main body 14.

る。 The water flowing on the glass hatch 15 collects on the shelf 14d of the backdoor main body 14, and mainly flows along the shelf 14d as shown by the arrow in FIG.
However, this flow is caused by the dam 18 of the buffer member 16.
blocked by. Then, the water whose flow is blocked is guided to the lower part of the back door body 14 by the weir part 18 and is discharged. Therefore, unlike the conventional case, the water does not flow to the seal portion 19 between the back door 11 and the vehicle body 12. As a result, even when used in a cold region, the seal portion 19 does not become icy, and the opening/closing function of the back door 11 is maintained.

しかも、この堰部１８を既存の緩衝部材１６に

4, between the lower edge 15b of the glass hatch 15 and the shelf 14d of the back door body 14, there is a lower edge 18 of the weir 18 of the buffer member 16.
a is present, the lower edge 15b of the glass hatch 15 is connected to the shelf 1 of the back door main body 14.
4d, and the shelf portion 14d is prevented from being scratched or the lower end edge portion 15b of the glass hatch is prevented from being chipped.

用上有益な効果を発揮する。Effects of the invention As explained above, according to this invention,
By forming a dam part on the buffer member that softens the impact when the glass hatch is closed, which blocks water flowing through the shelf of the back door body, the workability of assembling the back door is ensured without increasing the number of parts. Water can be prevented from flowing into the seal between the back door and the vehicle body, and the opening/closing function of the back door can be maintained. In addition, when attaching the glass hatch to the back door body, the dam of the buffer member can prevent the lower edge of the glass hatch from hitting the shelf of the back door body, which is a practical feature that can prevent damage to the glass hatch or the back door body. exert beneficial effects.
