<p>PURPOSE:To perform high-efficient operation without the occurrence of leakage by forming a partition wall such that a part thereof is positioned facing the peripheral edge part of a recessed part and pressing a valve body by the partition well. CONSTITUTION:Under a state in which a cylinder head 30 is mounted to a cylinder block 1, a partition wall 33 is formed in a manner that a part thereof is positioned facing a peripheral edge part 35a of a recessed part 35. When the cylinder head 30 is mounted to the cylinder block 1, the partition wall 33 presses a valve body 10 through a cylinder head gasket 22 and prevents bending of the valve body 10. This constitution prevents the occurrence of leakage even when a rubber-coated gasket is used, and performs high-efficient operation.</p> |
