<p><P>PROBLEM TO BE SOLVED: To provide a belt type continuously variable transmission capable of suitably and surely reducing an off-center of a belt and capable of restraining falling down of a fixed sheave. <P>SOLUTION: In this belt type continuously variable transmission, a winding radius of a belt B wound around a primary pulley 36 and a secondary pulley 37 disposed on a primary shaft SP and a secondary shaft SS rotatably supported in a casing is varied, achieving a desired speed ratio. At least one of the primary shaft SP and the secondary shaft SS is supported movably in the axial direction, and the belt type continuously variable transmission is provided with a first energizing means 70 energizing at least one of them to the axial direction from a movable sheave 38 side, and a second energizing means 80 energizing at least one of them to the axial direction from the fixed sheave 37 side and energizing to the axial direction while having an outer peripheral part of the fixed sheave 37 as the point of action. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
