In a combustion internal engine in which a cylinder head 8 is connected to a cylinder block 1 with a bolt 5 coming rough the cylinder head 8, more than half of a screw portion C of the bolt to be screwed in the cylinder block 1 is located under the central portion X of the depth of a water jacket 4. Since this portion of the cylinder block 1 is high in rigidity compared with the upper portion of the cylinder block, a gasket 9 can be tightened evenly.
