Abstract
An oil supply path passes through members separate from a cylinder head () to supply a lubricant to bearings () of camshaft journals. The oil supply path includes an oil supply passage () for the camshaft above the camshaft (), a connection passage () for the camshaft between the oil supply passage for the camshaft and an internal passage () in the cylinder head (), and branch oil passages () for the camshaft journals. Each branch oil passage branches off from the oil supply passage for the camshaft, and is connected to one of the bearings () from above. Each of the branch passages includes a throttle () with a smaller cross-sectional flow area than the oil supply passage for the camshaft.
