Abstract: A sealing structure of a main oil gallery for an internal combustion engine is provided to prevent oil leakage by improving a plug bolt fastening structure, and prevent a head of a plug bolt from being projected. A stepped threaded portion(10) having a diameter larger than that of a main oil gallery(200) of a cylinder block(100), is formed integrally with an end of the main gallery. A plug bolt(20) having threaded outer surface is joined to the stepped threaded portion. A gasket(30) is fitted between a steppe surfaces(11) of the stepped threaded portion and a stepped surface(21) of the plug bolt. The plug bolt has a head(20a) which is prevented from being projected from a top surface of the cylinder block.
