Abstract
A slide roller is provided. A lower connecting surface of the roller is never in contact with a roller passage surface. By taking advantage of a normal distance between a corner sliding surface and a center point of the roller greater than a vertical distance between an upper sliding surface of the roller and the center point, a pulley disc assembly can be started lightly, the acceleration in the middle stage of the slide stroke is increased, and speed transmission in the rear stage of the slide stroke is increased.
