PURPOSE:To widen an allowable temperature rnage of a thermostatic chamber, and to execute a very high temperature test and a very low temperature test by placing a gripping tool body and a gripping tooth in the inside of the thermostatic chamber, and placing a cylinder and a piston on the outside of the thermostatic chamber. CONSTITUTION:A test piece T.P is grasped by a pair of upper and lower gripping tools. Also, each gripping tool is constituted so that a gripping tool body 3 and a gripping tooth 4 are displaced relatively by a cylinder 1 and a piston 2, and the test piece T.P is grasped between the gripping teeth. The gripping tool body 3 and the gripping teeth 4 are placed in the inside of a thermostatic chamber 6, and the cylinder 1 and the piston 2 are placed on the outside of the thermostatic chamber 6. In this way, the test piece can be grasped in the inside of the thermostatic chamber by operating the cylinder and the piston in the outside of the thermostatic chamber, and also an allowable temperature range of the thermostatic chamber is widened, and the test piece can be tested at a very high temperature and a very low temperature. |
