ムシヤフトの軸受構造。[Claims for Utility Model Registration] A camshaft that drives intake and exhaust valves of an engine is rotatably supported by a cam cap in a journal part on a cylinder head, and an oil passage is provided in the camshaft,
In a bearing structure for an engine camshaft, an oil hole communicating with the oil passage and opening on the surface of the journal portion is bored in the camshaft, and a resin coating layer is formed on the sliding surface of the cam cap. Concave portions extending in the circumferential direction are provided in the sliding surface of the cam cap on both front and rear sides of the oil hole, and the thickness of the resin coating layer is thicker at the recessed portions due to the recessed portions. The bearing structure of an engine camshaft is characterized by being thinner in some parts.
