Abstract:
1. An endless power transmission belt-type continuously variable transmission comprising a drive pulley formed from a fixed-side pulley half and a movable-side pulley half, a driven pulley formed from a fixed-side pulley half and a movable-side pulley half, and an endless power transmission belt wound around a V-face of the drive pulley and a V-face of the driven pulley, a gear ratio being changed by increasing a groove width of one of the drive pulley and the driven pulley and decreasing a groove width of the other, wherein in that the V-faces of at least the fixed-side pulley halves of the drive pulley and the driven pulley have a straight-line shape for the generatrix of a portion that is radially further inside than a predetermined position and have a curved shape for the generatrix of a portion that is radially further outside than the predetermined position, the curved shape being curved in a direction that compensates for a misalignment of the endless power transmission belt.
