PROBLEM TO BE SOLVED: To provide a camshaft lubrication device which reduces an amount of an oil supplied from an oil pump to a sliding part of a camshaft thereby downsizing the oil pump and improves the lubrication performance of the sliding part of the camshaft at the time of the start of an internal combustion engine.SOLUTION: In a camshaft lubrication device, an oil dropping hole 23 is formed at a breather plate 19 of a cylinder head cover 3 so as to be positioned above a cam cap 12. In the cam cap 12, a groove 24 for receiving and storing an oil dropped from the oil dropping hole 23 and a communication hole 25 which allows the groove 24 and a sliding part 12a of the cam cap 12 to communicate with each other are formed. |
