Claims

[Scope of claims for utility model registration] 1. Head cover 2 of overhead valve camshaft engine 1
The tappet 6 is positioned below the cam 5 of the camshaft 4 of the valve train 3, and the tappet 6 is inserted into the tappet hole 8 of the tappet support wall 7 so as to be vertically slidable. An oil reservoir 9 is formed on the top surface in a shape that allows oil to be supplied to the tappet hole 8, and a blazer passage 12 is formed on the upper circumference of the camshaft chamber 10 that accommodates the camshaft 4 via an oil-proof cover 11. A tappet lubrication system for a valve train of an overhead valve camshaft engine is characterized in that the lateral edge 13 of the oil reservoir 9 is configured to overhang the oil dripping side edge 14 of the oil-proof cover 11 laterally outward. Tappet lubrication system for valve train of overhead valve camshaft engine. 2. Insert the oil dripping protrusion 16 into the camshaft chamber 10 from the middle of the inner peripheral surface 15 of the oil-proof cover 11 in the circumferential direction.
2. The tappet lubrication device for a valve train of an overhead valve camshaft engine according to claim 1, wherein the tappet lubrication device is provided so as to protrude toward the overhead valve camshaft engine.
