摘要:
A cylinder head bolt inserted into a cylinder head is threadingly engaged with an engine casing comprised of a cylinder and a crankcase to tighten the cylinder head and the engine casing firmly together. Between a rotation operating part, which is provided in a head of the cylinder head bolt, and an upper surface of the cylinder head, a plain washer and a spring member placed thereabove are interposed. The spring member is capable of exerting an axially acting spring force. A first frictional resistance between the rotation operating part and the spring member is so chosen to be lower than a second frictional resistance between the spring member and the plain washer and a third frictional resistance between the plain washer and a bearing surface on the cylinder head.
