Abstract:
A toroidal continuously variable transmission including input and output discs disposed to face each other so that a rotational axis of the input disc and a rotational axis of the output disc conform, each of the discs having a concave contact surface; a power roller sandwiched between the contact surfaces of discs so that the power roller is tiltable, the power roller transmitting a rotational driving force of the input disc to the output disc with a transmission ratio corresponding to a tilt motion angle; and a pressing device which presses one of the discs toward the other. When viewed from a direction of a tilt motion axis lof the power roller, the contact surface of at least one of discs has a region with a curvature that is larger than a curvature of a tilt motion trajectory of a contact surface of the power roller.
