Claims

[Claims for Utility Model Registration] An engine body side member having a semicircular protrusion;
A semicircular protrusion and a member to be attached to which is joined to a flat part around the protrusion, and a seal curved part corresponding to the semicircular protrusion and a flat part between the engine body side member and the attached member. In the engine seal device, the sealing member is provided with a sealing member that seals between the engine body side member and the attached member, the sealing member having a sealing flat portion corresponding to the sealing curved portion and a sealing flat portion corresponding to the sealing portion. A seal protrusion protruding toward the engine body side member is formed at the bent portion that connects with the seal flat part, while a protrusion that fits into the seal protrusion is formed on the engine body side member. A sealing device for an engine, characterized in that a fitting groove is formed.
