Abstract
A continuously variable transmission in which a sliding member is prevented from inclining is provided. The continuously variable transmission has a first oil passage provided in a movable sheave, and a second oil passage provided in a primary shaft supporting the movable sheave and connected in series to the first oil passage. A working oil is discharged from a hydraulic chamber via the first and second oil passages. The working oil is more difficult to discharge from the second oil passage than the first oil passage.
