A chain oil jet structure integrated with an oil pump is provided to reduce the pulsation of oil discharged from the oil pump and lubricate a timing chain, thus increasing productivity and reducing costs. In a chain oil jet structure integrated with an oil pump for reducing the pulsation of oil, an inlet port is provided at one position in the oil pump(10), and an outlet port(12) is provided at the other position in the oil pump. The chain oil jet structure is constructed so that oil is injected directly from the oil pump to a timing chain(20). An oil jet hole(13), which is formed in the outlet port of the oil pump in such a way as to communicate with the outside, is formed to face the timing chain.
