## Abstract

A glass run with a bottom wall, a vehicle outer side wall, and a vehicle inner side wall as a basic skeleton. The basic skeleton is attached to a door frame groove portion formed in a door frame, the glass run guiding upward and downward movement of a door glass. In the glass run, a vehicle inner side of the vehicle outer side wall is formed with a hard portion that comes into sliding contact with the door glass, the hard portion having a higher hardness than the hardness of a vehicle outer side wall body portion of the vehicle outer side wall.

## Claims

### Claim 1

A glass run with a bottom wall, a vehicle outer side wall, and a vehicle inner side wall as a basic skeleton, the basic skeleton being attached to a door frame, the glass run guiding upward and downward movement of a door glass, wherein
a vehicle outer side wall body portion of the vehicle outer side wall includes a stairstep shape with a portion between a distal part of the vehicle outer side wall body portion and a proximal part of the bottom wall side of the vehicle outer side wall body portion protruding to a vehicle inner side, and
the portion of the stairstep shape that protrudes to the vehicle inner side is formed with a thick portion in direct contact with and unembedded into the stairstep shape, the thick portion further protrudes toward the vehicle inner side, comes into sliding contact with the door glass, and the thick portion has higher hardness than hardness of the vehicle outer side wall body portion of the vehicle outer side wall.

### Claim 2 (depends on 1)

The glass run according to claim 1, wherein
the vehicle inner side wall is formed with a vehicle inner side seal lip that extends from a vehicle inner side wall tip end portion or a vehicle outer side between the vehicle inner side wall tip end portion and the bottom wall to a vehicle outer side and the bottom wall side, and having a side surface of a vehicle outer side in sliding contact with the door glass, and
a reaction force from a vehicle outer side and a vehicle inner side received by the door glass when the door glass comes into sliding contact with the hard portion and the vehicle inner side seal lip is larger on a vehicle inner side than on a vehicle outer side.

### Claim 3 (depends on 1)

The glass run according to claim 1, wherein a convex rib is formed on a side surface of a vehicle inner side of the hard portion.

### Claim 4 (depends on 1)

The glass run according to claim 1, wherein
the vehicle outer side wall is formed with a vehicle outer side seal lip that extends from a vehicle outer side wall tip end portion or a vehicle inner side between the vehicle outer side wall tip end portion and the bottom wall to a vehicle inner side and the bottom wall side, and has a side surface on a vehicle inner side in sliding contact with the door glass, and
the vehicle outer side seal lip does not come into contact with the hard portion.

### Claim 5 (depends on 1)

The glass run according to claim 1, wherein a vehicle outer side of the vehicle outer side wall is in surface contact with a door frame groove portion.

### Claim 6 (depends on 1)

The glass run according to claim 1, wherein the thick portion is not recessed into the stairstep shape.

### Claim 7 (depends on 1)

The glass run according to claim 1, wherein the portion of the stairstep shape that protrudes to the vehicle inner side is thicker than the distal part and the proximal part.

### Claim 8 (depends on 1)

The glass run according to claim 1, wherein the thick portion has higher hardness than hardness of the distal part and the proximal part and has an impedance that is adapted to match an impedance of the door glass.

### Claim 9 (depends on 1)

The glass run according to claim 1, wherein a surface of the thick portion on a vehicle inner side is formed with a plurality of ribs disposed continuously in the longitudinal direction and parallel to each other.

### Claim 10 (depends on 1)

The glass run according to claim 1, wherein the thick portion having the higher hardness is formed, continuously in the longitudinal direction, that comes into sliding contact with the door glass.
