PROBLEM TO BE SOLVED: To provide a vibration measurement device capable of acquiring a precise measurement result, even to a water pump bearing, in which finishing processing of a shaft end is not performed.SOLUTION: An arbor 17 is configured so that, a hole 17a parallel to a rotation shaft is provided on one end of a columnar shape, the other end is formed into a taper shape, and an elastic body disk formed of a disk-shaped elastic body, a disk-shaped base part, and a shaft, is arranged on a bottom part of the hole 17a. An end face of the elastic body disk presses a shaft end of a water pump bearing 13, thereby the elastic body absorbs inclination of a shaft end face, and prevents inclination of the shaft.SELECTED DRAWING: Figure 1 |
