PROBLEM TO BE SOLVED: To provide a resonance avoidance device that easily performs resonance avoidance of a vibrator by adjusting a natural frequency.SOLUTION: A resonance avoidance device includes: a first support frame 11 and a second support frame 13 that have a first mass member fitting part and a second mass member fitting part supporting a vibrator and freely detaching a first mass member 12 and a second mass member 14 and changing the fitting positions thereof in a longitudinal direction; and the first mass member 12 and the second mass member 14 that are provided to the support frames, respectively. Consequently, the resonance avoidance device easily performs resonance avoidance of the vibrator. |
