PROBLEM TO BE SOLVED: To provide a lubricating oil pump to increase a delivery amount per unit time. SOLUTION: Four pump parts 32, 33, 34, and 35 are arranged at the periphery of a cam part 31. In this case, each pump part sucks and discharges lubricating oil through reciprocation of a main piston rod 326 and a valve piston rod through rotation of a first eccentric cam 312 and a second eccentric cam between which a specified rotation direction phase difference is provided. The pump parts perform the same operation one by one during one full rotation of the two eccentric cams.
