Abstract
A toroidal-type stepless transmission includes: at least a pair of an input disc and an output disc; a power roller tiltably provided between the pair of the input disc and the output disc, the power roller being configured to transmit a driving force from the input disc to the output disc; and disc shrouds covering the input disc and the output disc, respectively. Each of the disc shrouds has an outer peripheral portion formed with an oil discharge groove configured to discharge an oil within each disc shroud to the outside, the oil discharge groove penetrating from an inner surface of the disc shroud to an outer surface of the disc shroud and extending in a circumferential direction of the disc shroud.
