Abstract:
In a cylinder head lubricating structure for an engine, in which a breather passage which guides, toward a cylinder head, gas including oil mist generated in a crank chamber by oil splashing means housed in the crank chamber so as to splash-oil in accordance with rotation of a crankshaft is formed in a crankcase, a cylinder block and the cylinder head to supply, toward the cylinder head, lubricating oil through the breather passage, a breather chamber with which an end portion, on the crank chamber side, of the breather passage communicates is formed in the crankcase, and a one-way valve preventing backflow of the oil toward the crank chamber is attached to the crankcase to be located between the crank chamber and the breather chamber. Accordingly, it is possible to supply a sufficient amount of oil to the cylinder head side even when the head difference between the crank chamber and the cylinder head is large.
