Abstract

A vibration generation device which can vibrate in only one axial direction is used to simultaneously load a vibration force in a plurality of axial directions onto a test piece, and to make it possible to easily modify the proportion of vibration force in each axial direction. The present invention includes: a vibration generation device connection part 1 which is connected to the vibration generation device and is vibrated in a z-axis direction; a first diaphragm 2 which is connected to the vibration generation device connection part 1 and extends in cantilevered form in an x-axis direction intersecting the z-axis direction; a second diaphragm 3 which is connected to the vicinity of an end of the first diaphragm 2 in the x-axis direction, and which extends in cantilevered form in the z-axis direction and a y-axis direction intersecting the x-axis direction; and a test piece installation part 5 on which the test piece is installed and which receives vibrations via the first diaphragm 2 and the second diaphragm 3 from the vibration generation device connection part 1, wherein at least one of the first diaphragm 2 and the second diaphragm 3 has a length adjustment mechanism 6.
