PROBLEM TO BE SOLVED: To provide a testing device capable of effectively testing attrition of synchro ring and a gear cone. SOLUTION: The testing device 20 is provided with an inertial unit 21, a driving unit 22 and a driven unit 23. For a 1st synchro part fixing part 31 provided with the inertial body 21, a 1st synchro ring 1a is provided, for a 2nd synchro part fixing pat 32 a 2nd synchro ring 1b is provided. For the driving unit 22, a 1st gear cone 2a is provided. For the driven unit 23, a 2nd gear cone 2b is provided. The 1st gear cone 2a can be rotated by means of a motor 60. The testing device 20 is composed of a 1st moving mechanism 25 moving the 1st gear cone 2a toward the 1st synchro ring 1a and a 2nd moving mechanism 26 moving the 2nd gear corn 2b toward the 2nd synchro ring 1b.
