ド潤滑用オイル通路。 Overlap the cylinder and cylinder head, connect the overlapping head cover or bearing housing with stud bolts, and align the lower and upper half shaft holes formed on the mating surfaces of the cylinder head and head cover or bearing housing to operate the valve. In a 4-cycle engine that supports a cam journal for the engine, the gap between the stud bolt insertion hole that passes through the cylinder head and the stud bolt is used as an oil passage, and a weight reduction is applied to the center of the lower bottom of the shaft hole on the cylinder head side of the cam journal. A recessed hole for the cylinder head is formed by casting, and an oil passage is drilled from the outer surface of the cylinder head, crossing the recessed hole to reach the stud bolt insertion hole, and the outer surface opening is attached and removed using a screw plug. An oil passage for lubricating the cylinder head of a four-stroke engine, which is characterized by being freely closed.
