Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a vehicle door structure, and more particularly to a flash surface structure.

(Prior Art) In recent years, vehicles, particularly automobiles, tend to be so-called flash surfaces in which stepped portions are excluded from the outer surface of the vehicle body as much as possible in order to improve aerodynamic characteristics.
Under such circumstances, as seen in Japanese Utility Model Laid-Open No. 60-114012, a door glass that can be raised and lowered is arranged outside a door frame that extends upward from the door body to achieve a flush surface for the door. It is known to do so.

In this type of door, it is necessary to clean the water between the door glass and the door frame because the door glass is arranged outside the door frame. In response to such a request, it is general to fix a weather strip to a door frame, and to provide the weather strip with a lip that covers the end portion of the door glass and abuts against the outer plate surface of the door glass.

By the way, recently, in a weather strip, a core material is embedded in the weather strip, and the weather strip is clipped to an opposing portion of a door frame, while the weather strip has a guide function of a door glass. Things are being developed. As a result, in this one, the weather strip can be firmly fixed to the door frame and its mounting workability can be improved, and further, the guide mechanism for the door glass can be
It is not necessary to provide it separately.

(Means and Actions for Solving Problems) However, in the above configuration, the door glass tends to be displaced in the vehicle exterior direction while the vehicle is traveling, and the core material is embedded in the weather strip including the lip to reinforce the weather strip. Therefore, the force of the door glass is transmitted to the weather strip via the lip, and the weather strip tends to be displaced (rotated) about the inner peripheral end of the facing portion. For this reason, fatigue will accumulate in the core material over time, and the clip force (holding force) of the weather strip must be gradually reduced.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a vehicle door structure that can more reliably hold a weatherstrip on a door frame while maintaining the function of guiding the doorstrip by the weatherstrip. It is in.

(Means and Actions for Solving Problems) In order to achieve the above object, in the present invention, a vertically movable door glass is arranged outside a door frame extending upward from a door body, The door frame is provided with a facing portion extending along the plate surface of the door glass, a weather strip is provided on the facing portion, and the weather strip has a main body extending along the facing portion of the door frame, A lip provided on the outer peripheral end side of the main body and in contact with the outer plate surface of the door glass; and a clip portion provided on the inner peripheral end side of the main body and clipped to the inner peripheral end portion of the facing portion. In a vehicle door structure in which a core member is embedded inside the weather strip so as to reach the lip from the clip portion through the body, a claw is provided at an outer peripheral end portion of the facing portion. Said pawl, wherein is engaged to the outer peripheral end side of the body to regulate the displacement in the outside direction, it is constituted.

With such a configuration, the length between the inner peripheral end and the outer peripheral end of the facing portion is effectively used as a moment arm, and the force of the door glass that tends to be displaced in the vehicle exterior direction during traveling is used. Based on this, it is possible to suppress the weather strip from displacing via the cored lip with a comparatively small force, and it is possible to prevent the holding force of the clip from decreasing. Therefore, the weather strip can be more reliably held on the door frame.

Moreover, the setting direction of the clip stopper is the same as the fixing direction of the claw, and if the clip stopper is used, the fixing by the claw is also performed. Therefore, the workability can be improved in mounting the weather strip.
