PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission capable of dispensing with a complicated control circuit even with a configuration of tilting a power roller by a fluid pressure, and a bicycle interior transmission hub using the same.SOLUTION: A first piston 7a can move a first trunnion 6a in a direction along a tilt axis Y direction using a hydraulic pressure. A male screw portion 71a of the first piston 7a is screwed with a female screw portion 63a of the first trunnion 6a. Owing to this, the first trunnion 6a moves in a second direction opposite to the first direction by tilting the first trunnion 6a in a first tilt direction to follow the movement of the first trunnion 6a in the first direction.

    【課題】流体圧でパワーローラを傾倒させる構成であっても、複雑な制御回路を必要としないトロイダル型無段変速機、及びこれを用いた自転車用内装変速ハブを提供する。【解決手段】第1ピストン7aは、油圧を利用して、傾転軸Y方向に沿う第1方向へ第1トラニオン6aを移動可能である。第1ピストン7aの雄ねじ部71aが第1トラニオン6aの雌ねじ部63aと螺合している。このため、第1トラニオン6aが第1方向に移動にすることに伴う第1トラニオン6aの第1傾転方向への傾転によって、第1トラニオン6aは第1方向とは反対の第2方向に移動する。【選択図】図4
