PROBLEM TO BE SOLVED: To provide a transport packing tester which is capable of simultaneous vibration test in XYZ axes, being small, light and low cost, and hardly limited in test locations. SOLUTION: The tester horizontally supports a vibration table 2 on a beam 1 via coil springs 3 in 4 corners on the backside and forms a test object 19 capable of holding with a holding tool 12 on the table surface 2a on the vibration table 2. On the backside of the vibration table 2, an attaching leg 7 provided to the rotation drive container 5 side in a vibrator 4 generating vibration of the frequency matching the rotation due to weight unbalance between the rotary shaft 5b of horizontal rotation driver 5a and the eccentric fly wheel 6a connected in one with a rotary shaft 5b is attached so that load of vibration in up and down, left and right and back and fourth directions is accepted by the vibration table 2. A vibrator controller 17 capable of controlling normal to reverse rotation of the rotation driver 5a in the vibrator 4 is provided. COPYRIGHT: (C)2007,JPO&INPIT
