Abstract: PROBLEM TO BE SOLVED: To compactly collect a mechanical section which dynamically balances a vertically movable base at a specified vertically moving location, especially at a continuously vertically moving location. SOLUTION: This vertically movable housing shelf is constituted of a hanging rope 29 and a rotary body. In this case, the hanging rope 29 hangs the vertically movable base which reciprocates between a reference height location and a lower location which is lower than the reference height location. The vertically movable base is gravitationally supported by a first rotating ring 22 through the first hanging rope 29. Then, a second hanging rope 26 is combined with a main body through a stretchable body of which the stretching force changes by stretching. A first moment between the first hanging rope 29 and the first rotating ring 22 dynamically roughly balances with a second moment between the second hanging rope 26 and a second rotating ring 21 at a specified or optional height location of the vertically movable base.  The rotation moments of the two rotating rings based on the tension of the two hanging ropes match and balance at a specified height location. The vertically movable base stops at the specified height location, and does not start moving by itself. Such a rest spot is not limited to one, and several spots could be set.
