DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass sealing structure for an automobile door.

[0002]

2. Description of the Related Art In a door glass opening of an automobile,
Some partition sashes partition the door glass opening in the front-rear direction of the vehicle body, and attach a movable door glass that can move up and down and a partition glass that is fixed in a constantly closed state. Since it is necessary to use sealing members having different shapes for the movable door glass and the partition glass, a glass run for the movable door glass is attached to the opening for the movable door glass, and an opening for the partition glass is provided. Is known to be fitted with a gasket for partition glass (for example, see Japanese Utility Model Laid-Open No. 2-233).

[0003]

However, in this case, a door weather strip is attached to an upper edge of the door panel from an upper edge of the opening for the movable door glass to an upper edge of the opening for the partition glass. The glass run for the movable door glass and the glass run for the partition glass were in contact with the door weather strip.

[0004] Therefore, the contact surface between the door weather strip and the glass run for the movable door glass and the contact surface between the door weather strip and the gasket for the partition glass are exposed on the side of the upper edge of the door glass opening. And the appearance is impaired.

[0005]

According to a first aspect of the present invention, there is provided an automotive door glass in which an opening for a movable door glass that can be raised and lowered and an opening for a fixed partition glass are partitioned by a partition sash. In the seal structure, a glass run disposed above the opening for the movable door glass receives the upper end edge of the movable door glass, and a vehicle interior side seal abutting the upper end of the movable door glass from the vehicle interior side. Part, and a molding part that covers the vehicle exterior of the hollow seal part, and the end of the glass run crosses the partition sash from the opening for the movable door glass along the upper edge of the partition glass. In the extended portion, the seal portion on the vehicle interior side is cut out, and the partition Upper edge of the gasket which is attached to the periphery of the is characterized in that fitted into the hollow seal portion.

Thus, the glass run extends from the upper edge of the movable door glass to the upper edge of the partition glass, and the upper edge of the opening for the movable door glass and the upper edge of the opening for the partition glass are continuously covered by the molding portion. .

According to a second aspect of the present invention, the gasket is provided with a projection projecting toward the hollow seal portion at a portion on the upper end surface of the partition glass.

As a result, the projection is pushed into the hollow seal portion, and the gasket on the upper edge of the partition glass is covered with the molding.
