軸の支持構造。 A driving camshaft and a driven camshaft are rotatably supported by respective bearings formed on a fixed frame, and are interconnected via helical gears fixed to these camshafts, and the bearings are It consists of a cylinder head and a cam cap that support the outer periphery of the camshaft, and both flanges formed on the camshaft so as to be located close to both sides of the cylinder head and cam cap, In a camshaft support structure in which a plurality of oil grooves are provided in the axial direction, a gap between the cylinder head side surface and the flange side surface on the thrust receiving side of the camshaft is defined as a gap between the cam cap side surface and the flange side surface. and an oil groove is provided on the inner periphery of the cam cap, and the oil groove communicates only with the oil groove on the outer periphery of the camshaft on the side opposite to the side receiving the thrust. Camshaft support structure.
