摘要： A sealing structure for a continuously variable transmission, which seals a clearance between a movable sheave and a cylinder. The continuously variable transmission may change a groove width of each pulley of the cylinder by moving a corresponding movable sheave though supply and discharge of a hydraulic pressure to and from the cylinder. The sealing structure includes an outer peripheral side seal member that is ring-shaped and disposed in a ring-shaped groove formed in one of the movable sheave and the cylinder; and an inner peripheral side seal member that is more elastic than the outer peripheral side seal member, ring-shaped, and disposed in a layered manner in the ring-shaped groove on an inner peripheral side with respect to the outer peripheral side seal member. A side of the outer peripheral side seal member where it contacts the inner peripheral side seal member is chamfered.
