PROBLEM TO BE SOLVED: To provide an under-floor housing container of a shallow type shallower than an under-floor depth, to secure and improve structural strength including the one of a deep type, to smooth the operation of an elevating and lowering drive mechanism or the like to provide a motor-driven type elevating and lowering drive under-floor housing container with excellent performance reliability. SOLUTION: For this motor-driven elevating and lowering under-floor housing container for freely housing a container body box mounted on a bottom plate under the floor and projecting it on a floor surface, a frame constitution body arranged under a floor is provided with the elevating and lowering drive mechanisms and the bottom plate is elevated and lowered by the elevating and lowering drive mechanism. Then, at the four corner parts of the bottom plate, all the overlap connection end parts of bottom frame angles 91 for constituting the bottom plate are fixed in a three-way bent state.
