Description

  The present invention relates to an outer garnish mounting structure that is mounted on the vehicle outer side of a door sash portion in a vehicle door including a door main body portion and a door sash portion that forms an opening window in the upper portion thereof.

A door for a vehicle includes a sash integrated door that integrally forms a sash portion called a press door and a door main body by pressing, and a sash portion that is roll-formed on a door main body portion that includes an outer panel and an inner panel. There is a roll sash door that is connected by joining.
The roll sash door can form a window frame by joining the pillar portion erected from the door main body portion and the roof portion located on the roof side of the vehicle by welding or the like, so it is less expensive than a press door. There are benefits.
However, when the lateral width of the pillar portion is gradually changed in the vertical direction due to a door lock mechanism, a door glass raising / lowering mechanism, or a design reason, it is difficult to cope with the roll molding alone.

Therefore, a method has been proposed that employs a structure in which a garnish that is wider than the pillar portion of the roll sash is attached so as to cover the outside of the pillar portion.
As a conventional garnish attachment method, a method in which a fixing hole is provided on the sash side and a garnish is fitted, or a method in which a bracket is joined to a pillar portion as shown in Patent Document 1 and a garnish is attached to this bracket is known.
However, in the method of providing the fixing hole on the sash side, the position where the fixing hole is provided must be away from the roof part due to the reason that a glass run is provided in front of the door of the pillar part. The gap with the garnish was unstable.
Further, in the method disclosed in Patent Document 1, the edge portion of the extension panel that extends from the pillar portion to the rear of the door is used to engage the engaging portion provided in the garnish, and the sash and the back surface of the garnish are elastic. Since only the sealing material is provided, the garnish is deformed in the wide and narrow directions in the direction in which the garnish floats and sinks with respect to the outer surface of the sash, and when the garnish is lifted, the gap between the garnish and the roof portion becomes large.
In addition, when the garnish is deformed in the direction in which it sinks, the appearance also deteriorates.
In addition, when the pillar portion of the sash is provided so as to be inclined rearward and downward from the roof portion toward the door body portion, the mounting position of the glass run for guiding the window glass is from the upper portion of the pillar portion to the door body portion. Therefore, a glass run bracket having a substantially triangular shape in front view in the indoor / outdoor direction for mounting the glass run is required.
However, since the glass run is continuously and smoothly formed from the roof portion toward the pillar portion, the glass run may be unstable in the range from the roof portion of the glass run to the glass run bracket. .
