Description

[Detailed explanation of the invention] This invention is a so-called sunroof (with a window opening provided in the roof).
The present invention relates to a roof water drainage structure for a moonroof type automobile.

In an automobile in which a roof 1 is provided with two openings 2 and 3 on the left and right as shown in FIG. Drip rails 21.degree. 31 are formed on the peripheral edge of the cover 3, respectively, so that the drop rails 21.degree.

However, if the car is parked on a slope and the car body is tilted to the left or right, water may accumulate in the center of the higher drip rail and overflow, causing water to enter the interior of the car. Occur.

In order to prevent this, conventional methods have been developed such as connecting drainage pipes to the central portions of both drip rails 21 and 31, or providing a communication pipe that communicates the central portions of both drip rails. In any case, in the conventional structure in which the pipe is joined to the drip rail, the work of blazing the end of the pipe into the drip rail is extremely troublesome1, and there is a possibility of water leaking from the blazed portion, which is not preferred in practice.

The present invention provides a water draining structure capable of solving the above-mentioned problems, and will be described below with reference to the embodiments shown in FIGS. 2 to 4.

In this invention, both drip rails 21.3 of roof panel 1
One or more communication recesses 4 whose bottom surfaces are at the same level as the bottom surface of the drip rail are formed in the opposing central part of the roof panel 1, and the recesses 4 formed in the roof panel 1 itself Both drip rails 21 and 31 are configured so that their central portions communicate with each other.

On the upper surface of the peripheral part of the recess 4, the recess 4 is connected to the roof panel 1.
The covering panel 5 is fixed by welding or the like so that it is flush with the roof surface of S.

Both side ends of the panel 5 are folded into both drip rails 21, 31, and cover the end surfaces of the recess 4, and there are drain portions 5 that communicate the drip rails 21, 31 and the recess 4.
Form 1.52.

According to the configuration of the present invention as described above, the communication recess 4 can be easily formed by press molding the roof panel 1, and both the drip rails 21, 31 and the recess 4 that communicates them are all formed in the roof panel 1. Since it is integrally formed, there is no risk of water leakage.

Moreover, since the panel 5 fixed to cover the recess 4 is provided overlapping the roof panel 1 and the top surfaces of the drip rails 21 and 31, welding work is not only easy, but also the welded portion is free from problems such as water leakage. There is no need to take this into account, and rainwater and the like can freely flow between the drip rails 21 and 31 through the concave portion 4 from the drain portions 51 and 52, which can bring about great practical effects.
