TOROIDAL-TYPE STEPLESS TRANSMISSION

摘要

A toroidal-type stepless transmission (1) is provided with: at least a pair of an input disc (15) and an output disc (17); and a power roller (19) which is provided in a tiltable manner between the pair of the input disc and the output disc and which transmits drive force from the input disc to the output disc. The stepless transmission (1) is also provided with disc shrouds (31, 33) which cover the input disc and the output disc. Oil discharge grooves (37, 39) are formed in the outer peripheries of the disc shrouds, and the oil discharge grooves penetrate through the disc shrouds from the inner surfaces to the outer surfaces, extend in the circumferential direction, and discharge oil within the disc shrouds to the outside.
