PURPOSE:To reduce the deflection of the core of a test piece, by mounting sealing members, which are provided with inner holes, whose diameter is smaller than the holding parts of the test piece on its parts, whose diameter is gradually increases. CONSTITUTION:On the side wall, an upper wall 14 and a bottom wall 15 of a corrosion liquid tank 5A, sealing members 12B and 12B are fixed by supporting plates 16. Inner holes 11, whose diameter is smaller than holding parts 4 of a test piece 4, are provided in the members 12B and 12B. A distance L between both members 12B and 12B is made equal to the distance between parts 3 and 3, whose diameter increases gradually. The holding parts 4 and 4 are held by rotary rods 13 and 13 at the outside of the liquid tank 5A. Even if the members 12B are deformed by corrosion liquid 7 in the liquid tank 5A, sealing is kept by the contact of the part 3, whose diameter increases gradually, and the holes 11. Thus the test piece 1 can be held in the vicinities of the parts 3, whose diameter gradually increases. |
