To provide a storage type supporting unit capable of sufficiently securing fall strength and of lifting/lowering long and heavy workpieces even in a constitution enabling storage in storing pits.
In fixed frames 10 fixed to the storing pits P, intermediate frames 20 are supported so as to be liftable/lowerable via linear guide mechanisms 40 (guide rails 41, sliders 42). In the intermediate frames 20, moving frames 30 are supported so as to be liftable/lowerable via linear guide mechanisms 50 (guide rails 51, sliders 52). Thus, even in the constitution enabling storage in the storing pits P, sufficient fall strength can be secured by enlarging superposing margins of the respective frames 10, 20, 30. Moreover, in this constitution, since the plurality of moving frames 30 disperse and support a plurality of portions of a workpiece, even when the workpiece is long and heavy, the workpiece can be securely lifted/lowered.
