摘要： In a system for lubricating a valve-operating mechanism in an engine including a head cover coupled to an upper end of a cylinder head, and a valve-operating chamber defined between the cylinder head and the head cover. An oil mist transfer means for transferring an oil mist in an oil tank, an oil recovery chamber for recovering the oil accumulated in the valve-operating chamber by suction and a breather chamber into which a blow-by gas is introduced from the valve-operating chamber lead to the valve-operating chamber. In the lubricating system, a gas-liquid separating chamber for separating oil drops from the oil mist fed from the transfer means to guide the oil mist containing no oil drops to the valve-operating chamber is disposed between the transfer means 61 and the valve-operating chamber. Thus, the oil mist containing no oil drops can be supplied to the valve-operating chamber to lubricate the valve-operating mechanism without a resistance.
