Abstract
A belt type continuously variable transmission includes a drive pulley having a fixed pulley half and a movable pulley half; a driven pulley having a fixed pulley half and a movable pulley half; and a metal belt. The metal belt includes a metal ring assembly having a plurality of endless metal rings laminated on one another and a plurality of metal elements supported on the metal ring assembly. The metal belt is wound around the drive pulley and the driven pulley. The movable pulley half of the drive pulley has a flexural stiffness higher than that of the fixed pulley half of the drive pulley, wherein it is difficult for the edges of the metal ring assembly to contact the metal elements and a V-face of the drive pulley.
