Zusammenfassung:	To provide a controller of a continuously variable transmission capable of reducing clamping force of a variator as much as possible without causing chains or the like to slip.SOLUTION: When a predetermined learning condition is satisfied, a TCU 40 constituting a controller 1 of a continuously variable transmission reduces clamping force of a secondary pulley 35 while input torque is substantially constant; acquires, as a learning value, the clamping force of the secondary pulley 35 when a gear ratio becomes a minimum value; and adjusts a target secondary pulley clamping force, which is a control target value of the clamping force of the secondary pulley 35, using the acquired learning value.SELECTED DRAWING: Figure 1 【課題】バリエータのクランプ力を、チェーン等がスリップしない範囲で、できる限り低減することが可能な無段変速機の制御装置を提供する。【解決手段】無段変速機の制御装置１を構成するＴＣＵ４０は、所定の学習条件が成立した場合に、入力トルクが略一定の状態で、セカンダリプーリ３５のクランプ力を下げて行き、変速比が極小値をとるときのセカンダリプーリ３５のクランプ力を学習値として取得し、取得した該学習値を用いて、セカンダリプーリ３５のクランプ力の制御目標値である目標セカンダリプーリクランプ力を調節する。【選択図】図１
