In a continuously variable transmission, a primary pulley includes a first fixed sheave coupled with an input rotation shaft, and a first movable sheave configured to move on the input rotation shaft in an axial direction of the primary pulley; and a secondary pulley includes a second fixed sheave, and a second movable sheave. At least one of the primary and secondary pulleys further includes an axially fixed wall configured to rotate together with the corresponding rotation shaft; and a movable cylinder configured to move together with the corresponding movable sheave, cooperating with the fixed wall to define a cylinder chamber of the corresponding pulley, and having a cylindrically-shaped opening axially outside of the cylinder chamber, the movable cylinder being laid out to permit the opening to axially overlap with at least a portion of a bearing which rotatably supports the corresponding rotation shaft.
