## Abstract

A glass run is attached to a door frame of an automobile to reduce intrusion of noise from an inside of a door of the automobile into an interior of the automobile through the glass run, while allowing a seal lip section to bend easily when a door glass is moved up and down. A partition wall having a reference surface is provided between a vehicle-interior-side seal wall and a vehicle-interior-side seal lip section. The reference surface contains: a first reference point located in the vicinity of a connection portion between the vehicle-interior-side side lip section and the vehicle-interior-side side wall; a second reference point which is on the vehicle-interior-side side wall and located closer to a bottom wall than the connection portion; and a third reference point located in the vicinity of a tip of the vehicle-interior-side seal lip section.

## Claims

### Claim 1

A glass run for being attached to a door frame of an automobile and guiding an upward movement and a downward movement of the door glass, comprising:
a bottom wall facing an end surface of the door glass;

a seal lip section for sealing between the door glass and the door frame, the seal lip section extending from a tip of the side wall toward the bottom wall; and
a partition wall provided between the side wall and the seal lip section, the partition wall having a reference surface containing (i) a first reference point located in the vicinity of a connection portion between the seal lip section and the side wall, (ii) a second reference point which is on the side wall and located closer to the bottom wall than the connection portion, and (iii) a third reference point located in the vicinity of a tip of the seal lip section,
the second reference point or the third reference point being located the lowest in a top-to-bottom direction of the automobile among the first reference point, the second reference point, and the third reference point.

### Claim 2 (depends on 1)

The glass run as set forth in claim 1, wherein the third reference point is located the lowest in the top-to-bottom direction of the automobile among the first reference point, the second reference point, and the third reference point.

### Claim 3 (depends on 1)

The glass run as set forth in claim 1, wherein the second reference point is located the lowest in the top-to-bottom direction of the automobile among the first reference point, the second reference point, and the third reference point.

### Claim 4 (depends on 1)

The glass run as set forth in claim 1, wherein:
the seal lip section and the partition wall are connected to each other without a gap therebetween; and
the side wall and the partition wall are connected to each other without a gap therebetween.
