Abstract
A roller construction for use on the lever arms of a front jaw of a ski binding. The rollers have a central opening therethrough which has a radially enlarging characteristic from the midlength portion thereof toward the axial end thereof. That is, the diameter of the opening adjacent the axial ends is greater than the diameter of the opening at the midlength portion thereof. The interior surface of the opening at the midlength portion thereof is rounded at a radius which is substantially greater than the diameter of the roller. The interior diameter of the roller at the midlength portion is generally equal to or preferably slightly larger than the diameter of the axle received in the opening. The contour of the wall of the opening facilitates a rocking or tilting of the roller relative to the axis of the axle. As a result, the roller can assume a tilted position relative to the axis of the axle as the ski boot sole shifts its position relative to the ski binding. Thus, the release of the ski boot from the ski binding is not hindered in any way.
