Abstract
A belt-type transmission includes a drive pulley, a driven pulley, and a V-belt. In at least a certain range of a low-speed layout, a pulley-groove V angle of a portion of a drive pulley where the V-belt is wrapped is larger than an average belt V angle when the V-belt is bent at a curvature corresponding to a wrapping diameter of the V-belt with respect to the drive pulley, and a pulley-groove V angle of a portion of a driven pulley where the V-belt is wrapped is larger than an average belt V angle when the V-belt is bent at a curvature corresponding to the wrapping diameter of the V-belt with respect to the driven pulley.
