CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PURPOSE: A bearing structure of a continuously variable transmission is provided to keep an appropriate belt alignment by holding bearing members of a primary shaft and a secondary shaft in regular positions against the tensile force of a belt and improve the durability of the continuously variable transmission. CONSTITUTION: A rotation shift mechanism(6) is stored in a housing member fixed in a casing(1), an input end of a primary shaft(3) is connected to the rotation shift mechanism(6), the primary shaft(3) is rotatably supported to the housing member via a bearing member, and radial positioning means are provided between the housing member and the casing(1) so as to be positioned on the outer circumference of the bearing member, so that the tensile force of the belt is directly received by the positioning means.
