Provided are: a toroidal continuously variable transmission that can achieve suitable oil feed both for lubrication at contact interfaces between a power roller and discs and for cooling of the power roller; and a drive mechanism-integrated electricity generation apparatus for an aircraft, the electricity generation apparatus including the toroidal continuously variable transmission. The toroidal continuously variable transmission includes: 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. The cooling outlet and the lubrication outlet are arranged such 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.
