PROBLEM TO BE SOLVED: To provide a method that measures a friction coefficient while a belt is in an endless state in a device for measuring the friction coefficient of the belt by the Euler method. SOLUTION: After an endless belt 2 is wound around a driving pulley 30, a driven pulley 40, and a load measurement pulley 50, a specific heavy weight W is set, the operation of the heavy weight W is cut by a pawl for preventing backward rotation, and a load cell 4 is operated. Then, the driven pulley 40 is locked for preventing rotation, a motor 10 is rotated, tension T2 at a slack side at this time and effective tension FP are measured by the load cell 4 and a torque-measuring instrument 5, respectively, and the Euler formula is used for calculating a friction coefficient.
