Claims

[Scope of utility model registration request]

It is approximately box-shaped with a bottom wall, part of which becomes the combustion chamber wall, and approximately vertical side walls along the direction of the cylinder row, and the cylinder head bolts that pass through boss portions formed along the side walls connect the cylinders. In a cylinder head of an in-line multi-cylinder internal combustion engine that is tightened and fixed to a block, a V-shape connecting the substantially central part of the bottom wall and the bolt seat at the upper end of the boss part and forming a flat plate along the direction of the cylinder row. An in-line multi-cylinder internal combustion engine characterized in that an intermediate wall is formed and the thickness of the V-shaped intermediate wall is set such that the rigidity of the V-shaped intermediate wall is relatively higher than the rigidity of the side wall and the boss portion. cylinder head.
