Abstract
A first plate portion abuts against a cylinder head and has a substantially constant plate thickness. A second plate portion abuts against a cylinder block and has a substantially constant plate thickness. An intermediate plate portion is sandwiched between the first plate portion and the second plate portion and has a substantially constant plate thickness. A shim is sandwiched between the first plate portion and the intermediate plate portion and is disposed over an entire periphery of a peripheral edge of a combustion chamber hole. The shim includes a gradually changing portion. The gradually changing portion has a thickness in the hole axis direction that becomes thicker with a separation from the peripheral edge of the combustion chamber hole.
