PURPOSE:To attain easily manufacture and maintenance check by constituting a titled device so that it has a hole for inserting an oscillation transfer mechanism part and an oscillating shaft, and also has an upper seal plate on which an airtight seal is provided between this hole and the oscillating shaft, and an oscillatable bellows. CONSTITUTION:As for a testing device, an upper seal plate 6 provided with a hole for inserting an oscillating shaft 3 provided with a test piece upper fitting base 2 for fitting a test piece to the lower part end, and a lower seal plate 20 are connected and formed so as to hold airtightness, on both ends of an socillatable bellows 7. According to such a constitution, an oscillation transfer mechanism part is not exposed in a high temperature or an atmospheric gas, therefore, it is unnecessary to consider a heat resistance and an atmosphere resistance, a manufacture is executed easily, a price is stabilized, and a maintenance check is attained easily. |
