ンダヘツドのオイル通路構造。 An oil entry passage formed in the cylinder head to introduce lubricating oil from the cylinder block side of the internal combustion engine, an oil introduction passage communicating with the oil entry passage, and an oil introduction passage oriented in the axial direction of the camshaft held in the cylinder head. In the oil passage structure of the cylinder head, the cylinder head has a main oil passage that communicates with the oil introduction passage, and a plurality of oil distribution passages that guide lubricating oil from the main oil passage to each part of the camshaft. An oil passage structure for a cylinder head, characterized in that a part of the main oil passage with which the introduction passage communicates is arranged at a higher position than other parts of the main oil passage.
