PROBLEM TO BE SOLVED: To maximize acceleration levels in all directions, e.g. in X, Y and Z axial directions especially in a range of low frequency by arranging a vibration assembly under a table top plate. SOLUTION: A vibration table assembly 10 for laboratory provided with a side wall is provided with a table top plate 12 for fix a specimen for vibration test on the upper side thereof. A lower structure supporting member 16 is provided under the table top plate 12 with an insulation layer 14 in between, and one or more kind of vibration assembly 18 among of pneumatic reciprocating piston vibration machine 17, a double-piston pneumatic randum vibration machine 19, etc., is fitted to a supporting body 6. In order to increase an acceleration level in a range of low frequency, the table top plate 12 made of aluminum is provided with a number of patterned cut parts, to reduce its weight, and in the lower structure supporting member 16, the same treatment is done to reduce its weight.
