## Abstract

A vehicle window glass raising-and-lowering mechanism is achieved which can prevent a window glass from tilting, caused by a carrier plate rotating, even if the carrier plate is lowered down to a bottom dead point so that the window glass is fully open. The carrier plate includes a point of force that receives a movement force from wires in a downward direction. Two stopper members are provided at separated positions with respect to the vehicle forward and rearward direction, and the two stopper members have a positional relationship that crosses over either side of the point of force of the carrier plate.

## Claims

### Claim 1

A vehicle window glass raising-and-lowering mechanism comprising:
a carrier plate having a window glass mounted thereto;
a wire connected to the carrier plate, the wire configured to raise and lower the carrier plate; and
stopper members that restrict a lower-movement extremity of the carrier plate by the stopper member coming into contact with the window glass or the carrier plate,
wherein the carrier plate includes a point of force that receives a movement force from the wire in a downward direction,
wherein two of the stopper members are provided at separated positions with respect to the vehicle forward and rearward direction, and the two stopper members have a positional relationship that crosses over either side of the point of force of the carrier plate, and
wherein the two stopper members are provided at mutually offset positions, in the vehicle width direction crossing over the point of force.

### Claim 2 (depends on 1)

The vehicle window glass raising-and-lowering mechanism according to claim 1, wherein the two stopper members come into contact with the carrier plate.

### Claim 3 (depends on 2)

The vehicle window glass raising-and-lowering mechanism according to claim 2, further comprising a guide rail on which the carrier plate is supported in a raisable and lowerable manner,
wherein the two stopper members are provided on the guide rail.

### Claim 4 (depends on 1)

The vehicle window glass raising-and-lowering mechanism according to claim 1, wherein at least one of the two stopper members is provided on a vehicle door panel or a door sash, on which the carrier plate and the wire are provided.
