Claims

[Scope of utility model registration request]

A pair of conical plate-shaped pulleys are fitted into at least one of a drive shaft and a driven shaft that are pivotally supported on a machine frame so as to face each other in a V-shaped pulley groove, and at least one of the pulleys is slidable in the axial direction. None, equipped with a variable pitch pulley mechanism in which the distance between opposing pulleys, that is, the width of the pulley groove, is variable, and at least one of the pulley groove surfaces on the drive shaft side and the driven shaft side has an annular transmission with a V-shaped cross section. A variable pitch pulley continuously variable transmission characterized in that a medium ring is circumscribed and clamped, a adjusting band is wound around the outer circumference of the ring, and the ring is used as a transmission medium between the pulley groove surface and the adjusting band. .
