PURPOSE: To lower the height of the main body of an apparatus, to obtain stability by lowering the center of gravity, and to simplifty the handling, by reducing the weight, by providing a running block between the fixed end of a wire rope and a fixed block.
CONSTITUTION: A running block 16 is provided at a part of a wire rope 4. The running block 16 is moved up and down by a wire rope 18, which is wound and unwound by a motor 17 that is provided in a main body 1. In order to move a sample holder 5 by 2l, the running block 16 is allowed to move by l, based on the principle of work. Therefore, the height of the main body 1 of the apparatus can be lowered by the difference, and the entire apparatus can be made compact and light-weight. Therefore, the apparatus is stabilized, and the attachment and detachment of the main body 1 of the apparatus and a container at the replenishment of coolant can be performed readily.
