PROBLEM TO BE SOLVED: To provide a vibration measurement device that reduces influences of vibration of the device itself and accurately measures vibration of a measurement target.SOLUTION: A vibration measurement device includes: a frame member 1 having a communication part into which a measurement target 100 is inserted; running support means 2, 3 which are formed on both ends of the frame member 1 and provided so as to protrude toward a center of an opening 1c that continues to the communication part, abutted to the outer surface of the measurement target 100 inserted into the communication part to support the frame member 1 to the measurement target 100, and also capable of moving in the longitudinal direction of the measurement target 100; and vibration measuring means 4 for measuring vibration of the measurement target 100. The vibration measuring means 4 includes: an abutting member 41 for being abutted to the measurement target 100; a vibration detector 42 integrally provided with the abutting member 41; and driving means 44-49 for switching the abutting member 41 between abutting and non-abutting states to the measurement target 100.SELECTED DRAWING: Figure 3 |
