PURPOSE:To easily and precisely perform vibration test including inclined and horizontal vibration under a condition including temperature, humidity or the like, by sealing a part between a bottom wall part provided with a hole into which an exciting shaft is inserted with sealing material and top plate part with a cornice-like peripheral wall body. CONSTITUTION:A part between the bottom wall part 7 provided with the hole 10 into which the exciting shaft 3 is inserted with the sealing material 11 and the top plate part 8 interlocked with the bottom wall part 7 through a spring protecting cylinder 19, a coil spring 17, a strut, etc. is sealed with the cornice- like peripheral wall body 9 which is freely open upwards to form an air-conditioning tank. Consequently the deterioration of airtight and adiabatic property due to the pressure change of the air-conditioning tank which is caused by the capacity change due to vibration is prevented and a body 5 to be tested is easily attachable/detachable. When vibration and rotation around a horizontal axial center C is performed in one united body with an external container 2, inclined and horizontal exciting is also executed. Thus the vibration test including the inclined and horizontal vibrations can be easily and precisely performed under various temperature and humidity conditions. |
