Description

  The present invention relates to a movable roof panel drainage structure using a movable roof panel that opens and closes a roof of an automobile, a body panel, and a weather strip that seals between a front pillar and a door glass.

In an open car type automobile, as shown in FIG. 7, the movable roof panel 6 is attached by being pulled out from the rear of the vehicle body 1 in the front direction. When the movable roof panel 6 is closed, the tip of the movable roof panel 6 comes into contact with a weather strip mounted on the body panel 4 on the upper side of the windshield 7.
The windshield 7 is held by the front pillars 3 on both sides thereof, and held by the body panel 4 on the upper side.

  As shown in FIG. 8, the conventional seal structure of the body panel 4 and the movable roof panel 6 is provided with a roof weather strip 120 attached to the body panel 4, and the roof weather strip 120 and the front end of the movable roof panel 6 and the body panel. It is performed by sealing between 4. The roof weather strip 120 is in contact with the body panel 4 or a molding 4a attached to the body panel 4 and a portion where the first seal lip 121 abuts against the front end of the movable roof panel 6 and the first seal lip 121. The second seal lip 122 is in contact with the rear surface of the movable roof panel 6 on the rear side, and the attachment base 123 is attached to the body panel 4 or the substantially U-shaped retainer 4b attached to the body panel 4.

Further, a drainage lip 125 is provided on the outer surface on the front side of the first seal lip 121 so that rainwater or the like leaking from between the body panel 4 or the molding 4a attached to the body panel 4 and the first seal lip 121 does not enter the inside of the vehicle. (For example, refer to Patent Document 1).
In this case, the rainwater received by the drainage lip 125 passes through the drainage groove 126 formed between the drainage lip 125 and the first seal lip 121 and is discharged to the front pillar 3 side that is both sides of the vehicle body. .

  The rainwater discharged to the front pillar 3 side reaches the front pillar weather strip 150 attached to the front pillar 3 side (the retainer 3 provided on the front pillar), and a hole 153 formed in the front pillar weather strip 150. Flows in. Then, it flows down through the gap between the hollow seal portion 151 of the front pillar weather strip 150 or the mounting base portion 152 and the front pillar 3 side, and is discharged outside the vehicle.

  In this case, however, the connecting portion between the front pillar weather strip 150 and the roof weather strip 120 must be molded by molding, and a slit for core removal must be formed in the mounting base 152. Unexpectedly, there was a risk that rainwater flowing in from the slit portion would flow into the vehicle. Moreover, the effort and cost for forming the hole 153 in the connection part will increase.

  Also, the seal lip of the roof weather strip is gradually deformed along the upper edge of the windshield, and rainwater flowing between the roof weather strip and the body panel is discharged along a groove formed in the front pillar. (For example, refer to Patent Document 2). However, in this case, rainwater flowed from the groove of the front pillar to the door glass side during traveling, which was not preferable.

Furthermore, at the connecting portion between the roof weather strip and the front pillar weather strip, a drain hole is formed in the end wall, along the groove formed in the front pillar weather strip for rain water between the roof weather strip and the body panel. (For example, refer to Patent Document 3). However, also in this case, it is necessary to form a drain hole in the end wall at the connection portion, which increases labor and cost.
