In a continuously variable transmission, a primary pulley (4) includes a first fixed sheave (40) coupled with an input rotation shaft (23), and a first movable sheave (41) configured to move on the input rotation shaft in an axial direction of the primary pulley; and a secondary pulley (6) includes a second fixed sheave, and a second movable sheave. At least one of the primary and secondary pulleys (4,6) further includes an axially fixed wall (43) configured to rotate together with the corresponding rotation shaft (23,24); and a movable cylinder (42) configured to move together with the corresponding movable sheave (41), cooperating with the fixed wall (43) to define a cylinder chamber (4a) of the corresponding pulley (4,6), and having a cylindrically-shaped opening axially outside of the cylinder chamber (4a), the movable cylinder (42) being laid out to permit the opening to axially overlap with at least a portion of a bearing (13) which rotatably supports the corresponding rotation shaft (23,24).
