WINDOW REGULATOR

摘要

In a window regulator, a positioner is provided between a pair of slider bases and a pair of windowpane holders and define a relative position therebetween in a forward/rearward direction of a vehicle; a vehicle-widthwise-directional wall is provided on each guide rail; and a pair of forward/rearward directional guide walls is provided on each slider base to hold an associated vehicle-widthwise-directional wall in the forward/rearward direction and to guide an associated slider base along an associated guide rail. A clearance in the forward/rearward direction between the vehicle-widthwise-directional wall of one guide rail and the forward/rearward-directional guide walls of one slider base is set smaller than that between the vehicle-widthwise-directional wall of the other guide rail and the forward/rearward-directional guide walls of the other slider base.

1. A window regulator comprising:
a pair of guide rails which are spaced from each other in a forward/rearward direction of a vehicle and extend in a vertical direction; a pair of slider bases which are supported by said pair of guide rails to be movable up and down along said pair of guide rails, respectively; a pair of windowpane holders which are fixed to said pair of slider bases, respectively, and hold a windowpane; a positioner which is provided between said pair of slider bases and said pair of windowpane holders, wherein said positioner defines a relative position between said pair of slider bases and said pair of windowpane holders in said forward/rearward direction; a vehicle-widthwise-directional wall which is formed on each of said pair of guide rails and extends in a widthwise direction of said vehicle; and a pair of forward/rearward directional guide walls which are formed on each of said pair of slider bases to hold an associated said vehicle-widthwise-directional wall therebetween in said forward/rearward direction and to guide an associated slider base of said pair of slider bases along an associated guide rail of said pair of guide rails, wherein a clearance in said forward/rearward direction between said vehicle-widthwise-directional wall of one of said pair of guide rails and said pair of forward/rearward-directional guide walls of one of said pair of slider bases which is associated with said one of said pair of guide rails is set smaller than a clearance in said forward/rearward direction between said vehicle-widthwise-directional wall of the other of said pair of guide rails and said pair of forward/rearward-directional guide walls of the other of said pair of slider bases.
