Claims

[Claims for Utility Model Registration] An input shaft, an output shaft disposed parallel to the input shaft, a first fixed sheave concentrically fixed to the input shaft, and a first fixed sheave concentrically supported by the input shaft. and a first movable sheave that is biased toward the first fixed sheave and is slidable in the axial direction of the input shaft; and an input pulley that is concentrically fixed to the output shaft. a second fixed sheave; and a second movable sheave that is supported concentrically on the output shaft, is biased in a direction approaching the second fixed sheave, and is slidable in the axial direction of the output shaft. an output pulley comprising: a conical engagement surface formed on opposing surfaces of both sheaves of the input pulley; and a conical engagement surface formed on opposing surfaces of both sheaves of the output pulley. and an endless drive band made up of the metal block bodies connected together, the endless drive band being stretched between the input pulley and the output pulley so as to be frictionally engaged with both edges of the metal block bodies, A first fixed sheave fixed to the input shaft and a second fixed sheave fixed to the output shaft are positioned so as to frictionally engage with different side edges of the endless drive band. and the gear ratio which is the ratio of the rotation speed of the output pulley to the viewpoint speed of the input pulley of the continuously variable transmission is at least one of the maximum value and the minimum value of the continuously variable transmission, When a line connecting the width center positions of the input shaft and the output shaft of the metal block body of the endless drive band along the rotation center axis is projected onto a plane including the rotation center axis, the line becomes a straight line perpendicular to the rotation center axis. A continuously variable transmission characterized in that the relative positions of the first fixed sheave and the second fixed sheave are determined as follows.
