Zusammenfassung:	PROBLEM TO BE SOLVED: To correctly measure the elastic deformation amount of a rod-like member with a simple structure in rotating the rod-like member in an elastic deformation range. SOLUTION: In this measurement device, a shaft 14 is rotatably supported by a ball bearing 16 and a roller bearing 18. The measurement device is provided with: a holding mechanism 20 for blocking vibration or the like of the ball bearing 16 and the roller bearing 18; a driving mechanism 22 capable of rotating the shaft 14 at a rotational speed reaching an elastic deformation range; a connection mechanism 24 for connecting the shaft 14 to the driving mechanism 22 in a non-contact manner by using magnetism; and a displacement detection mechanism 26 disposed corresponding to a nearly central part in the axial direction of the shaft 14 for detecting the displacement of the shaft 14.
