PROBLEM TO BE SOLVED: To hold a material to be heated without influence of a change of an elastic force of a synthetic resin or temperature change even by mounting foldable legs at a mounting stage. SOLUTION: Supporting shafts 14 of legs 3 are supported by supporting holes 13 provided at the mounting stage 1, and the legs 3 are foldable by its rotation. When the legs are stood or folded, the legs 2 can be automatically fixed only by a rotating operation. With this constitution, a material to be heated of a weight which cannot be held by an elastic force of a synthetic resin can be high-frequency heated by using the stage without influence of a change of the force of the resin according to a temperature change in a heating chamber.
