フトのスラスト軸受構造。[Claims for Utility Model Registration] A cam cap is attached to a cylinder head of an engine and rotatably supports a camshaft, and when the camshaft is supported by the cam cap, both sides of the cam cap are attached. In the thrust bearing structure of the camshaft, a thrust supported portion of the camshaft is in contact with the camshaft, and the camshaft is supported by the thrust supported portion and the cam cap so that the camshaft can only move by a minute clearance in its axial direction. , an oil groove extending at a certain angle to the axial direction of the camshaft and through which oil can pass is bored in the sliding surface of the cam cap;
A thrust bearing structure for a camshaft, wherein one end of the oil groove is opened on one side of the cam cap, and the other end of the oil groove ends within the sliding surface.
