To provide a multiaxial testing device for eliminating an installation space, by imparting three degrees of freedom for vibration on an exciting point.

The multiaxial testing device 1 tests the vibrational characteristics of an object X to be tested, by imparting vibration to the object X to be tested, and includes a single base 2 and at least three exciting means 3a-3c for generating vibration in the axial direction. The exciting means 3a-3c are connected to the single base 2 on a support point side, while directing the axial direction in mutually differing directions, and installed to be connected to a single exciting point P on the acting point side.
