Claims

[Scope of utility model registration request]

The engine consists of a cylinder head whose upper part is covered with a cylinder head cover and a cylinder block that overlaps the cylinder head from below, which are tightened and fixed with through bolts that pass through the cylinder block. Equipped with a valve-based lubrication system,
The through bolt is attached so that its upper end is exposed in the valve train installation space surrounded by the cylinder head cover and the cylinder head, and the through bolt is attached to the through bolt so as to extend in its longitudinal direction. A communication hole communicating with the valve system installation space is bored, and a lower end opening of the communication hole is connected to a lubricating oil supply source so that the communication hole becomes a part of the valve system lubrication system. An engine lubricating device characterized by:
