徴とするカム軸のスラスト軸受構造。 In a thrust bearing structure for a camshaft, a thrust bearing groove for forming a thrust bearing surface is formed in the cylinder head, and an annular flange formed on the camshaft is fitted into the thrust bearing structure to regulate thrust fluctuations of the camshaft. Thrust surfaces are formed on both sides of the annular flange of the shaft in the axial direction in proximity to the annular flange, and journal portions for the radial bearing of the camshaft are formed in the cylinder head portions on both sides of the thrust bearing groove corresponding to the thrust surfaces. form,
An annular oil groove connected to a lubricating oil supply source via an oil passage is formed around the annular flange and between the thrust bearing groove and the lubricating oil is thereby supplied to the thrust bearing surface and the journal portion. Features a camshaft thrust bearing structure.
