Claims

[Scope of utility model registration request]

The winding groove 20 of the drive pulley 18 provided on the drive shaft 17 and the relay pulley 4 provided on the relay shaft 40
A first belt 46 is wound around the first winding groove 43 of the relay pulley 41 and a winding groove 47 of the driven pulley 34 provided on the driven shaft 33. 48 is wound around the belt winding transmission device, both winding grooves 4 of the relay pulley 41
3 and 44 have groove widths in the axial direction that gradually become narrower as they go inward in the radial direction, and partition portions 45 of both of the winding grooves 43 and 44 are movable in the axial direction. The relay shaft 40 is configured such that the pitch diameter of both winding grooves 43 and 44 of the relay pulley 41 can be changed by moving in the axial direction.
A continuously variable transmission mechanism for a belt-wound transmission device, characterized in that when moving away from one of a drive shaft 17 and a driven shaft 33, it is movable so as to approach the other.
