を特徴とするエンジンのロッカアーム部潤滑装置。In an engine using a dispersion lubrication system in which an oil hole is formed from the outer periphery of the rocker arm to the sliding part with the rocker shaft on the inner periphery, an oil groove is formed in the circumferential direction with a part of the oil hole side left on the rocker shaft, and A protrusion that matches the cross-sectional shape of the oil groove is provided on the inner periphery of the rocker arm and is inserted into the oil groove, and the rocker arm swings to connect the oil hole and one end of the oil groove to allow oil to flow into the engagement protrusion. While supplying the oil into the oil groove on one side bordering on the oil groove, the end of the oil groove on the other side and the oil hole are kept in a disconnected state, and the oil on the disconnected side is removed by swinging movement of the engagement protrusion into the oil groove. The oil in the groove is pressurized to supply oil to the sliding part, and the oil supply to the oil groove and the pressurized oil supply are alternately carried out using the protrusion into which the oil is inserted as a boundary. A lubricating device for the engine rocker arm.
