には、それぞれカーボンパウダ７が介在されている。In FIG. 2, the test piece TP is housed in the high temperature furnace 1. This device applies a bending load to the five test pieces TP by the punch 2 to continuously bend-test each test piece TP. Five bending support jigs 4 provided on five support bases 3 are provided. Have. Both the support base 3 and the support jig 4 are made of SiC ceramics. Each fulcrum jig 4 has a pair of bending fulcrums 5, and each test piece TP is bridged and held between the bending fulcrums 5 of each fulcrum jig 4.
The bending fulcrum 5 is also made of SiC ceramics. As shown in FIG. 1, the bending fulcrum jig 4 and the support base 3 are separated from each other, and the support jig 4 is detachably fitted into the groove 6 of the support base 3 to be assembled. The support bases 3 are also separated from each other, and are arranged so as to be adjacent to and in contact with each other. Each fulcrum jig 4 is also separated from each other. Here, carbon powder 7 is interposed between the fulcrum jig 4 and the support base 3, and between the bending fulcrum 5 and the support jig 4, respectively.

まま残り、接合が防止される。In such a high temperature test, O 2 in the atmosphere gas of the high temperature furnace 1 was used to form SiO 2 (silica) on the surfaces of the SiC ceramic support base 3, fulcrum jig 4 and bending fulcrum 5.
When both members are brought into direct contact with each other as in the conventional case, both members are joined to each other and cannot be removed. However, when the carbon powder 7 is interposed as in this embodiment, the carbon powder is heated by heating in the atmosphere, for example. 7 burns and the residue remains between both members to prevent joining. Therefore, replacement work of the damaged support jig 4 and the bending fulcrum is facilitated. Note that the carbon powder 7 remains as it is in a vacuum or in an inert gas to prevent bonding.
