することを特徴とするＶベルト式無段変速機。[Claims for Utility Model Registration] Variable-width pulleys are provided on the input shaft and output shaft, and a V-belt is wound between these two variable-width pulleys to adjust the groove width of each variable-width pulley. In a V-belt continuously variable transmission in which rotational force is transmitted from the shaft to the output shaft with a stepless gear ratio, at least one of the input shaft and the output shaft is mounted so as to be movable in the axial direction with respect to the housing. At the same time, an actuator for moving the shaft in the axial direction is provided between the movable shaft and the housing, and an actuator is provided between the movable shaft and the housing, and according to the amount of misalignment of the V-belt that occurs as the groove width of the variable width pulley changes. A V-belt type continuously variable transmission characterized in that the actuator is driven and the misalignment is corrected by shaft movement.
