To ensure compactness of a continuously variable transmission case.

An oil path 207, 257 is formed inside a support member 201, 251 for positioning an output disc 24 on a primary shaft 12. The oil path 207, 257 is opened to a through hole 202, 252 to insert the shaft 12 therein. A first/ second oil path 163, 164 is formed inside the primary shaft 12. The oil path 163, 164 is opened to a peripheral surface of the shaft 12 in a part positioning the through hole 202, 252. A seal ring 208, 208, 258, 258 is provided to prevent a leak of oil by interposing an opening. A route for supplying operating oil and lubricating oil to the oil path 163, 164 in a shaft side from the oil path 207, 257 in a side of the support member can be constructed, by eliminating necessity for forming an oil path in a side wall 150d of a transmission case 150, its shortening is obtained by this unnecessary component.
