PROBLEM TO BE SOLVED: To secure the working angle of a drive shaft and the radial size of a speed reduction mechanism in a two-axis belt continuously variable transmission.SOLUTION: A belt continuously variable transmission 10 comprises: a torque converter 12 to which output rotation of an engine 5 is input; a primary pulley 14 to which output rotation of the torque converter 12 is input; a secondary pulley 15 to which rotation of the primary pulley 14 is transmitted via a belt 16; a speed reduction mechanism 17 to which rotation of the secondary pulley 15 is input; and a differential mechanism 18 to which output rotation of the speed reduction mechanism 17 is input. The primary pulley 14 and the torque converter 12 are disposed in order from an engine 5-side so that the torque converter 12 is coaxial with the primary pulley 14, and the differential mechanism 18, the speed reduction mechanism 17, and the secondary pulley 15 are disposed in order from the engine 5-side so that the differential mechanism 18 and the speed reduction mechanism 17 are coaxial with the secondary pulley 15.

    【課題】2軸のベルト無段変速機において、ドライブシャフトの折れ角及び減速機構の径方向の寸法を確保する。【解決手段】ベルト無段変速機10は、エンジン5の出力回転が入力されるトルクコンバータ12と、トルクコンバータ12の出力回転が入力されるプライマリプーリ14と、プライマリプーリ14の回転がベルト16を介して伝達されるセカンダリプーリ15と、セカンダリプーリ15の回転が入力される減速機構17と、減速機構17の出力回転が入力される差動機構18と、を備える。プライマリプーリ14と同軸上に、エンジン5側から順にプライマリプーリ14、トルクコンバータ12が配置され、セカンダリプーリ15と同軸上に、エンジン5側から順に差動機構18、減速機構17、セカンダリプーリ15が配置される。【選択図】図1
