PURPOSE: Oil supply structure for lubricating a camshaft journal is provided to smoothly supply oil to the journal of a camshaft by changing the position of an oil supply hole guiding the flow of oil toward the journal of the camshaft. CONSTITUTION: An oil gallery(33) is formed in the axial direction of a camshaft(20). An oil supply hole(34) of which one side is communicated with the oil gallery is connected to a bolt hole(35) for bolt-connecting a cam cap(40). An oil line(42) is additively formed between the lower portion of a connecting hole(41) of the cam cap and the inner face of a cam bearing(44) to guide the oil guided to the outlet of the oil supply hole to the journal of the camshaft.
