Abstract:
A continuously variable transmission, comprising:a casing member; a continuously variable transmission mechanism including a primary pulley provided on a primary shaft, a secondary pulley provided on a secondary shaft, and a belt suspended between the primary pulley and the secondary pulley and enabling transmission of a motive force between the primary pulley and the secondary pulley and that, by changing a groove width of one of the primary pulley and secondary pulley relative to a groove width of the other, enables continuous adjustment of a speed-change ratio; a motive-force connection/disconnection mechanism that, by being connected to one of the primary shaft and the secondary shaft, enables connection/disconnection between an input side element for the motive force and an output side element for the motive force; a housing member fixed within the casing member and accommodating therein the motive-force connection/disconnection mechanism and rotatably supporting via a bearing member the one of the primary shaft and the secondary shaft connected to the motive-force connection/disconnection mechanism; a load-receiving element provided at a first side of the motive-force connection/disconnection mechanism and in coincidence with an imaginary line which perpendicularly intersects the one of the primary shaft and the secondary shaft and passes through the bearing member or in the vicinity thereof, to support the housing member with respect to the casing member, and adapted to receive a force acting upon the housing member toward the other one of the primary shaft and the secondary shaft; and a support member provided at a second side of the motive-force connection/disconnection mechanism opposite the first side and connected to the housing member.
