PROBLEM TO BE SOLVED: To provide an abrasion tester capable of efficiently testing durabilities of a rotary shaft and a bearing metal. SOLUTION: This abrasion tester 11 for testing abrasion conditions of the bearing metal 31 and a sliding part of the rotary shaft 33 supported rotatably by the bearing metal 31 is provided with a shaft support part 27 for supporting the rotary shaft 33 rotatably by the bearing metal 31, an electric motor 19 for rotation-driving the rotary shaft 33, and an eccentric weight 34 for imparting an eccentric load to the rotary shaft 33 under rotation. The first lubrication oil pump 22 for supplying a lubrication oil to the electric motor 19 is provided as a separate system independent each other from the second lubrication oil pump 38 for supplying the lubrication oil to the rotary shaft 33 and a sliding part of the the bearing metal 31. The abrasion tester 11 reproduces truly an operation condition where the rotary shaft 33 and the bearing metal 31 are attached onto an actual equipment to carry out not only the test for the durability, but also a test under a severe condition execution-incapable in the actual equipment.
