BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seal structure for an openable roof vehicle in which a vehicle body opening formed in an upper portion and a rear portion of a vehicle compartment is opened and closed by a movable roof.

[0002]

2. Description of the Related Art As is well known, various types of open / close roof vehicles, which are so-called convertible sedans capable of opening / closing the roof of a vehicle body, are provided (see, for example, Japanese Utility Model Laid-Open No. 1-165716). ).

That is, in the openable roof vehicle 1, as shown in FIG. 5 , a vehicle body opening 2 is formed in an upper portion and a rear portion of a vehicle compartment, and the vehicle body opening 2 can be opened and closed by a movable roof 3. The movable roof 3 includes a front roof 3a made of a hard synthetic resin plate that covers the upper portion of the vehicle body opening 2, and a rear roof 3b that is foldably connected to the front roof 3a and covers the rear portion of the vehicle body opening 2. . The rear roof 3b is formed of a rigid body such as a synthetic resin material, and both lower ends of the rear roof 3b are rotatably supported by the vehicle body 1 through a pair of pivotally supporting members, and a back window glass 4 is attached to the center thereof. ing.

A storage space 5 for accommodating the movable roof 3 when the vehicle body opening 2 is opened is provided at the rear portion of the vehicle body. The storage space 5 has an upper opening pivotally supported at the rear end portion of the vehicle body. The storage cover 6 is opened and closed. A weather strip 7 made of a synthetic rubber and having a circular cross section is attached to the periphery of the upper opening of the storage space 5. The weather strip 7, 6
As also shown in FIG. 5, the storage space other than the location of the movable roof 3 is fitted and fixed to the flange portion 8 which is erected on the peripheral edge of the opening of the storage space 5 via the notch portion which is cut out in the radial direction. 5 is disposed on the periphery of the upper opening.

On the other hand, a substantially linear seal member 9 is provided at the rear edge of the rear roof 3b. The seal member 9 is made of a synthetic rubber material, and has a base portion 9a fixed to the rear end edge of the rear roof 3b with an adhesive or the like, and a seal that integrally has a lower end portion of the base portion 9a and forms a drip channel 10 inside. It is mainly composed of a lip 9b.

When the vehicle body opening 2 is closed, the movable roof 3 folded in the storage space 5 is pulled out, slidably moved to a predetermined position along the periphery of the vehicle body opening 2 and stopped by a predetermined stopper. For example, both ends 7a of the weather strip 7 and both ends 9c of the seal member 9 are continuously joined at the same time when the closing work is completed. Subsequently, when the storage space 6 is closed with the storage cover 6, the storage space 5 is sealed by being pressed against the inner peripheral edge of the storage cover 6, the upper edge of the weather strip 7 and the upper end of the seal lip 9b. There is. Thus, for example, rain water or the like flowing along the rear roof 3b from front roof 3a is 6
As shown by the arrow, it reaches the drip channel 10 of the seal member 9 and is divided into both sides to be discharged to the outside through the trough portion 11 on the outer peripheral side of the weather strip 7.

[0007]

In the conventional seal structure for a retractable roof vehicle, as described above, when the movable roof 3 is in use, the weather strip 7 and the seal member 9 face each other at the opposite end portions 7a, 7a. 9c is joined to ensure the continuity between the drip channel 10 and the gutter portion 11, but since the weather strip 7 and the sealing member 9 seal once, a sufficient sealing action can be obtained. Absent. That is, on the front end side of the storage space 5, as shown in FIG. 7, the storage cover 6 comes into contact with both the upper end edge of the base portion 9a of the seal member 9 and the upper end portion of the seal lip 9b to obtain a sealing action, but the drip channel 10 Is a single
When the flow velocity of rainwater flowing down along the rear roof 3b is fast and the flow rate is large, the leading edge of the storage cover 6 and the base portion 9a.
There is a risk that it may overflow from the drip channel 10 through the gap between the above and the above, and may run over the seal lip 9b as it is and drip into the storage space 5.

On both sides of the storage space 5, especially weather
-Both ends 7a of the strip 7 and both ends 9 of the seal member 9
At the abutting portion of c, since the inner edge of the storage cover 6 merely abuts on the upper edge of the weather strip 7, when the rainwater or the like has a high flow velocity and a large flow rate as described above, the storage space 5 is further increased. Rainwater etc. easily leaks into the interior.

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned problems of the prior art, and stores the vehicle body rear portion from a use position that covers a vehicle body opening formed in an upper portion and a rear portion of a vehicle compartment.

An outer gutter 43 is provided between the seal lip 40 and the sub seal 41, and an inner gutter 44 is provided between the sub seal 41 and the main seal 42.

Then, both ends 28a, 28a, 37a, 37 of the first and second weather strips 28, 37 are formed.
a are each continuously against a use state of the movable roof 23
The sub seals 31 and 41, the main seals 33 and 42, and the inner and outer gutter portions 34, 43, 35, and 44 are continuously butted with each other. Further, the upper ends of the sub-seals 31 and 41 and the main seals 33 and 42 respectively contact the inner peripheral portion of the lid 26 when the lid 26 is closed.

Therefore, according to this embodiment, the movable roof 23 is pulled out from the storage space 25 to be used,
In addition, in a state where the upper opening of the storage space 25 is closed by the lid 26, rainwater, car wash water, and the like that have fallen onto the vehicle body travel along the front roof 23a and the rear roof 23b (back window glass 24) and then the first weather strip 28 is discharged. It flows through the upper side of the seal lip 32 and flows into the outer gutter 34, and normally the whole flows along the sub-seal 31 and wraps around to the outer gutter 43, 43 side of the second weather strip 37 on both sides to reach the rear end of the vehicle body. It is discharged to the outside through the provided drainage pipe 50. However, the outer gutter 3 such as rainwater
4 has a high inflow velocity and a large flow rate, a part of the water overflowed in the outer gutter 34 flows through the space between the sub seal 31 and the inner end surface of the lid 26 into the inner gutter 35 as it is. Then, it is reliably received by the main seal 33. Therefore, the inside of the inner gutter portion 35 is divided into the right and left parts and wraps around the inner gutter portions 44, 44 of the second weather strip 37, and is quickly discharged from the drain pipe 50 to the outside.

As described above, rainwater or the like is used for the outer gutters 34, 43.
Even if the sub seals 31 and 41 are crossed over from the above, the seals further flow into the inner gutter portions 35 and 44 and are guided to the outside, and the main seals 33 and 42 reliably block the inflow to the storage space 25. Completeness is obtained, and as a result, rainwater or the like can be reliably prevented from dripping into the storage space 25.

If the gutter portions 34, 35, 43 and 44 are set relatively deep, the sealing effect of the sub seals 31 and 41 and the main seals 33 and 42 is further promoted.

[0020]

As is apparent from the above description, according to the seal structure for the openable roof vehicle of the present invention, particularly the lid
When the body is closed, the first and second ends are opposed to each other .
Since the weather strip is provided with a double inner / outer seal portion and the inner / outer double gutter portion is provided on the outer peripheral side of the inner / outer double seal portion, the sealing performance is further improved, and even if heavy rain or car wash water is applied. It is possible to reliably prevent the rainwater and the like from dripping into the storage space.
