Abstract

A sealing structure capable of reducing oil leakage while preventing the oil from being deteriorated by a temperature rise of the oil.The sealing structure is configured to seal a clearance between two members tightly by a seal ring interposed therebetween. The seal ring is provided with a slidable structure, which is configured to seal the clearance between the two members by a hydraulic pressure applied thereto, and to unseal the clearance between the two members by a relative movement thereof resulting from a thermal expansion thereof.
