Filed: 2016-04-07
Abstract: PROBLEM TO BE SOLVED: To provide a technology capable of securing sealability on a position where fastening force of a fastening bolt hardly acts on an engine member with a simple constitution.SOLUTION: A communication opening 47 communicated to a water jacket HWJ for a head, is formed on a contact face 42b of a flange portion 24b disposed on a side wall portion 28a of a cylinder head 2 in a projecting manner. A flange thickness of a part on which fastening force of a head fastening bolt hardly acts, of the contact face 42b is determined to be thicker than a flange thickness of a part on which the fastening force of the head fastening bolt effectively acts, of the contact face 42b. Thus rigidity of the part on which the fastening force of the head fastening bolt hardly acts, becomes more than rigidity of the part on which the fastening force of the head fastening bolt effectively acts, and the fastening force can be easily transmitted to the part where the fastening force does not effectively act. As a result, sealability can be easily secured without increasing the fastening force of the head fastening bolt.SELECTED DRAWING: Figure 7
