Claims

[Scope of utility model registration request]

A long groove-shaped cooling channel along the combustion chamber is provided on the joint surface with the cylinder block, and the cooling water supplied to the water jacket of the cylinder block is passed through the cooling channel and then transferred to the water jacket formed inside the cooling channel. In the cylinder head in which the cooling channel and the water jacket of the cylinder head are connected, holes are formed at right angles inward of the cylinder head from the slope formed at the end of the cooling channel, and the water jacket is connected to the water jacket. A cooling waterway connection structure for a cylinder head, characterized in that the cooling waterway is connected to the cylinder head through a drilled hole opened to the cylinder head.
