Document Type and Number:

WIPO Patent Application WO/2016/175104

Kind Code:

A1

Abstract:

A cylinder head mounting section has a bolt hole formed in a cam holder, the bolt hole allowing a bolt for affixing a cylinder head to a cylinder to extend therethrough, the bolt hole also allowing lubricating oil to flow therethrough. A protrusion is formed integrally with the cam holder, protrudes from the cylinder head mounting section toward an intake valve or an exhaust valve, and conducts lubricating oil flowing from the upper end of the bolt hole. A guide section is formed as a separate body from the protrusion and extends toward the intake valve or the exhaust valve. The guide section includes a lubricating oil receiving section for receiving, below the protrusion, lubricating oil flowing along the protrusion. At a position located at a distance from the cylinder head mounting section, an extension section extends downward from the lower end of the protrusion toward the lubricating oil receiving section.
