Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle door structure having a door sash.

[0002]

2. Description of the Related Art Conventionally, as a vehicle door structure provided with a door sash, for example, Japanese Utility Model Laid-Open No. 58-14371.
There is one disclosed in Japanese Patent No.

In this publication, an inner member (door inner panel) and an outer member (door outer panel) in which a sash portion and a panel portion are integrally formed are provided, and the panel portions of the inner member and the outer member are aligned with each other. According to the above, there is disclosed a door structure in which a door body is formed by the both panel portions and a door sash is formed by the sash portions of the inner member and the outer member by combining the sash portions.

On the other hand, in automobiles, when a step is generated between the outer surface of the door sash and the outer surfaces of the pillars and the roof side on the vehicle body when the door incorporated in the vehicle body is closed, the external appearance is reduced. There is a possibility that the appearance may be impaired, and the sealing property and airtightness between the weather strip mounted on the outer periphery of the door sash and the vehicle body may deteriorate, which is not preferable. Therefore, it is desirable to prevent such a step from occurring.

[0005]

However, when the above-mentioned inner member has a structure that inclines or curves toward the vehicle interior side with respect to the outer member, the inner member or the outer member is molded and taken out from the molding device. Then, the sash portion and the panel portion try to return to the current state by the springback force.

Moreover, since the inner member and the outer member are slightly different in material composition and plate thickness for each product,
When the inner member or the outer member is molded and taken out from the molding apparatus, the amount by which the sash portion and the panel portion try to return to the current state due to the springback force is slightly different. The same applies to the pillars on the vehicle body side.

When the inclination of the sash portion toward the vehicle compartment side with respect to the panel portion (door body) does not fall within the allowable dimensional error due to the springback force or the assembly error, or the vehicle interior of the vehicle body side pillar Inclination error to the side may occur.

In this case, as described above, a step is formed between the outer surface of the door sash and the outer surfaces of the pillars on the vehicle body side and the roof side, so that the appearance is impaired or the door sash is damaged. This is not preferable because there is a possibility that the sealing property, airtightness, etc. between the weather strip mounted on the outer periphery and the vehicle body side may deteriorate.

Therefore, according to the present invention, when there is a possibility that the degree of inclination of the door sash toward the vehicle body with respect to the door body may not be within the allowable dimensional error, or the inclination of the vehicle body side pillar toward the vehicle interior side. Even if there is some error in the degree, etc., correct the inclination of the door sash toward the vehicle interior with respect to the door body,
An object of the present invention is to provide a vehicle door structure capable of preventing a step from being formed between the outer surface of the door sash and the outer surface of the vehicle body.

[0010]

In order to achieve this object, the present invention provides a door main body in which peripheral portions of a door inner panel and a door outer panel are joined to each other, and an upper portion of the door main body is provided. In a vehicle door structure provided with a door sash, a lower end portion of the door sash formed separately from the door body is fixedly disposed between the both panels, and an upper edge of the door inner panel is provided. A protrusion that abuts on the door sash is formed on a portion of the door sash, and a rib that is in contact with the door inner panel is a lower end portion of the door sash. It is characterized in that it is a door structure for automobiles provided in.

[0011]

According to this structure, the inclination of the door sash toward the vehicle body with respect to the door body may not be within the allowable dimension error or the inclination of the vehicle body side pillar toward the vehicle interior. If there is some error in the degree, etc., the step of the multi-stage positioning part of the rib provided at the lower end of the door sash is scraped off one step at a time, so that the door sash formed separately from the door body By arranging the lower end between both panels of the door body and correcting the inclination of the door sash toward the passenger compartment with respect to the door body when the ribs are brought into contact with the inner panel,
Make sure there is no step between the outer surface of the door sash and the outer surface of the vehicle body side pillar.
