PROBLEM TO BE SOLVED: To provide a lightweight vibrator suited to a model experiment in a centrifugal field. SOLUTION: The vibrator 10 has a hydraulic cylinder 11 having a cylinder body 17 and an advancing and retracting cylinder rod 18 in relation to the cylinder body 17, corresponding to the hydraulic pressure applied to the cylinder body 17. The cylinder rod 18 side of the hydraulic cylinder 11 is fixed to an exciting object, and the exciting object is excited by action of the cylinder body 17 as an inertial mass, corresponding to telescoping of the hydraulic cylinder 11 by application of the hydraulic pressure.
