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 partwhich is connected to the vibration generation device and is vibrated in a z-axis direction; a first diaphragmwhich is connected to the vibration generation device connection partand extends in cantilevered form in an x-axis direction intersecting the z-axis direction; a second diaphragmwhich is connected to the vicinity of an end of the first diaphragmin 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 parton which the test piece is installed and which receives vibrations via the first diaphragmand the second diaphragmfrom the vibration generation device connection part, wherein at least one of the first diaphragmand the second diaphragmhas a length adjustment mechanism
