PROBLEM TO BE SOLVED: To provide an operation characteristics measuring device for rotation linear motion transducing mechanism, capable of measuring transducing efficiency of work of the rotation/linear motion transducing mechanism at high precision. SOLUTION: The operation characteristics measuring device 5 includes a torque-measuring device 6 provided with a function for inputting torque to a ring shaft and a function for measuring the size of the torque input to the ring shaft and a weight-measuring device 7, provided with a function for inputting thrust weight to a sun shaft and a function for measuring the size of the thrust weight input to the sun shaft. The weight-measuring device 7 includes a spring 71A for generating the thrust weight, and a coupling mechanism 73 for inputting the thrust weight of the spring 71A to the sun shaft. A tightening pin 77 for the coupling mechanism 73 is constituted so as to input the thrust weight of the spring 71A through a spherical input part 77 to the sun shaft. COPYRIGHT: (C)2008,JPO&INPIT
