Description

  The present invention relates to a wire type window regulator that guides a carrier supporting a window glass with a guide rail.
Conventionally, various wire type window regulators have been known in which a wire is wound around a drum and a wire guide, the drum is driven to reciprocate the wire, a carrier that supports the window glass is attached to the wire, and the window glass is moved up and down. It has been.
The window regulator of Patent Document 1 is configured such that a carrier plate (carrier) is guided by a guide rail, and is moved up and down by a cable (wire) that is wound around the drum and the wire guide.
However, the window regulator described in Patent Document 1 has a glass holding portion projecting forward from the guide rail on the carrier plate, and glass is attached thereto, and the carrier plate slides on the guide rail. There is a distance in the front-rear direction to the place where the glass is supported. Further, the wires are routed in parallel away from the guide rails, and the positions where the wires are also attached to the carrier plate are separated from the positions where the guide rails slide. In either case, a moment for rotating the carrier plate about the sliding portion of the guide rail acts on the carrier plate. For this reason, a large load is applied to the carrier plate when raising and lowering the glass, and the window glass tends to roll in the front-rear direction, causing a shift between the direction of the sash that guides the window glass and the movement direction of the glass. Has the disadvantage of becoming unstable. In addition, since the carrier plate hits only one side of the guide rail, rattling is likely to occur when the carrier plate is raised and lowered.
In the window regulator of Patent Document 2, a glass holder is attached to a lower end portion of a window glass, while a carrier plate is attached to a slider slidably fitted in a guide rail having a groove section, and the glass is attached to the carrier plate. The holder is fixed. A wire stretched outside the guide rail is attached to the carrier plate.
The window regulator has a structure in which the window glass is supported by a carrier plate, and the carrier plate is attached to a slider and guided by a guide rail. For this reason, not only the weight of the window regulator increases, but also the assembly work is complicated. Further, since the carrier plate projects greatly on both sides of the guide rail and is connected to the glass holder at the tip thereof, the window glass easily rotates in the front-rear direction.
Japanese Patent No. 4365585 JP 2004-60372 A
