Abstract:
Provided is a continuously variable transmission (10) that can obviate the need for hole punching for providing an oil passage in a cartridge and pipes for conveying the oil to the oil passage of the cartridge. The continuously variable transmission comprises: an axle (11); a first disk (12) that has a curved raceway surface (13), and that integrally rotates with the axle; a second disk (14) having a raceway surface (15) that opposes the raceway surface of the first disk; a roller (25) pressed against the two raceway surfaces; and a carriage (29) that rotatably supports the roller. The axle includes: an oil passage (19) that extends through the inside of the axle in the axial direction; and a plurality of openings (20, 22) that extend from the oil passage to the outside in the radial direction and open to the outside of the axle. The openings are formed at least at the position of the second disk and between the two raceway surfaces.
