METHOD AND APPARATUS FOR MEASURING FORCIBLE FORCE OF ROD-LIKE MEMBER

PROBLEM TO BE SOLVED: To correctly and easily measure forcible force of a rod-like member having an intermediate joint without being influenced by vibratory force. SOLUTION: A forcible force measuring unit 15 includes a base 30 and a supporting means 31 for rotatably supporting a propeller shaft 1. The base 30 includes an upper base 37 having a detector supporting part 37a provided via a vibration control device 36 on a lower base 35. The supporting means 31 includes a frame 40 formed with a flange 40a and a height adjusting means 41 for attaching a center bearing 3. The flange 40a of the frame 40 is mounted on four detectors F1 to 4 provided on the supporting part 37a of the upper base 37. The height adjusting means has a height of a forcible force generation point O of an adjustable joint 2 positioned at the same height as the center in a height direction of the detectors F1 to 4.
