To provide a vibration measuring structure and a method for measuring vibration using this which can easily and inexpensively evaluate vibration suppression effects of vibration suppression member under conditions closer to the state used in an actual bearing device.

In the vibration measuring structure and the method for measuring vibration of bearing ring member 2 of this invention, by fitting a damping member 6 consisting of a ring shape suppressing alloy to the outer ring 7, an internal strain is given to the suppressing member 6, the bearing ring member 2 is put on a pair of support member 3 supporting the bearing ring member by contacting in line at a position to be a node of vibration in the outer circumferential surface 2a of the bearing ring member 2, the inner side of the bearing ring member 2 is hit with a hammer 4 to vibrate the bearing ring member 2, the vibration of the bearing ring member 2 is detected from the outer side of the part hit with the hammer 4 and grasp the attenuation characteristic of vibration.
