PROBLEM TO BE SOLVED: To provide a vibration testing machine, capable of conducting displacement control and load control for a model, and capable of conducting multi- directional load control. SOLUTION: This vibration testing machine simulates a material body other than a testing body 2 out of testing objects as a pseudo-model and excites the testing body 2 by a parallel link mechanism. The device is provided with the first calculation means 12 for calculation a response displacement of the pseudo-model, based on acceleration and reaction force provided by vibrating the testing body 2, a second calculation means 13 for conducting kinematic operation of the parallel link mechanism, based on the response displacement calculated in the first calculation means 12, and at least one excitation means 10 for exciting the testing body 2 by the parallel link mechanism, based on a calculated result calculated hereinbefore in the second calculation means 13.
