Abstract

The present disclosure reduces the displacement or fall of a glass run caused by temperature changes. A rivet 40 penetrates a planar opposing portion 10 of a sash and a planar mounting portion 22 of a trim strip in a thickness direction to fasten the planar opposing portion 10 and the planar mounting portion 22 together in the thickness direction. A base 31 of a glass run 30 is provided with an engagement protrusion 36 arranged adjacent in a lengthwise direction of an automobile to a swaged portion 42 of the rivet 40.

First claim

The invention claimed is:

1. A configuration of a glass run attached to a sash, of a door of an automobile having a cabin, to which a trim strip that is formed of a different member from the sash is fastened with a rivet, the glass run sealing a gap between the sash and a door glass held by the sash, wherein
the glass run comprises a base, an inner sidewall extending from an inner end of the base located inside of the cabin, an outer sidewall extending from an outer end of the base located outside the cabin, an inner seal lip extending from the inner sidewall toward an inner surface of the door glass facing inside of the cabin to come into contact with the inner surface, and an outer seal lip extending from the outer sidewall toward an outer surface of the door glass facing outside of the cabin to come into contact with the outer surface,
the trim strip includes a planar mounting portion facing the base of the glass run, the planar mounting portion being stacked in a thickness direction on a planar opposing portion of the sash, the trim strip further including a planar vertical portion extending substantially in a vertical direction and continuously from an end of the planar mounting portion facing the outside of the cabin,
at least an outer surface of the planar vertical portion is made of metal or plated with a metal,
the rivet penetrates the planar opposing portion of the sash and the planar mounting portion of the trim strip in the thickness direction, with first and second ends of the rivet both protruding from a stack of the planar opposing portion and the planar mounting portion, so as to fasten the planar opposing portion and the planar mounting portion together in the thickness direction, and
the base is provided with an engagement protrusion having an engagement surface arranged adjacent in a lengthwise direction of the automobile to the second end of the rivet protruding toward the base,
the engagement surface has a recessed portion on which the second end of the rivet fits, and
the recessed portion is an arc-shaped surface having a curvature equal to or greater than that of a peripheral surface of the second end rivet.

2. The configuration of claim 1 , wherein
the engagement surface has a larger dimension in a widthwise direction of the automobile than the second end of the rivet.

3. The configuration of claim 1 , wherein
the planar mounting portion of the trim strip is arranged on a surface of the planar opposing portion of the sash opposite to the base, and
the engagement protrusion has a protruding end face arranged to abut on the planar opposing portion of the sash.

4. The configuration of claim 1 , wherein
the glass run has a corner portion at an end of the glass run in the lengthwise direction, the corner portion being a die-molded portion, and
the engagement protrusion is formed in the die-molded portion.
