PURPOSE:To realize uniformity of a sensible temperature to electronic parts by interlocking and connecting in an endless shape plural electronic parts placing shelves running on an annular guide rail, and containing all the shelves in a load test high temperature tank. CONSTITUTION:A horizontal endless upper guide rail 2 and a lower guide rail 2' are provided concentrically on the inside of a high temperature tank 1 for executing a load test extending over many hours under a high temperature with respect to electronic parts, and the outside of the tank 1, respectively. A vertical shelf frame 4 having a wheel rolling on the rails 2, 2' is placed in multiple, and each frame is interlocked and connected. The frame 4 is provided with a fork- like shelf 8 for placing a magazine rack 7 into which a lot of electronic parts are inserted, and a contact 9 for supplying a direct current to the electronic parts. Therefore, the inside of the tank 1 does not receive a thermal bad influence from the outside, further increases uniformity of a sensible temperature to the electronic parts, therefore, the heat management is executed easily.
