<P>PROBLEM TO BE SOLVED: To provide a friction testing device without generation of a deviation in the parallelism between a specimen and a friction element and a fluctuation in the contact pressure between them, and providing a proper and reliable evaluation. Ž<P>SOLUTION: The friction testing device tests by contacting the friction element 24 to the specimen S mounted on a table 3 in a load condition by a load mechanism 11 and reciprocating the table 3. The load mechanism 11 includes a measurement head 17 having the friction element 24 and a load cell 25, two balance arms 14, 15 having a counterweight 22, and a post 12, in which a four-node parallel link mechanism is formed with them. The counterweight 22 is attached so that an axis thereof is perpendicular to the balance arm 15 in the longitudinal direction and the center G of the gravity of the counterweight 22 itself is lower than the balance arm 15 on a lower side.
