1. A toroidal continuously variable transmission comprising:
input and output discs opposed to each other;
a power roller tiltably held between the input and output discs to transmit rotational drive power of the input disc to the output disc at a speed ratio determined by a tilt angle of the power roller;
at least one lubrication outlet that discharges an oil toward at least one contact interface between the input or output disc and the power roller; and
at least one cooling outlet that discharges the oil toward the power roller, wherein
the cooling outlet and the lubrication outlet are arranged such that when the power roller is viewed along a rotational axis of the power roller, an imaginary extension of an axis of the cooling outlet is directed toward a point closer to the rotational axis of the power roller than a point toward which an imaginary extension of an axis of the lubrication outlet is directed and that a distance between the cooling outlet and a point at which the oil discharged from the cooling outlet contacts the power roller is smaller than a distance between the lubrication outlet and the contact interface.
