Abstract
A roller unit of a window regulator is movably engaged with a guide rail of a U-shaped cross section. The guide rail has a pair of parallel side walls one of which is formed with a longitudinal groove of a V-shaped cross section and the other is formed to be planar. The roller unit includes a pair of convexly surfaced rollers in rolling contact with the grooved side wall and a flat surfaced roller in rolling contact with the planar side wall. The flat surfaced roller is movable toward and away from the planar side wall and urged against the same by a spring.
