ABSTRACT:
The invention provides a moving mechanism which can be made so small and lightweight as to be portable when being contracted, which can be formed into a longer higher column than conventional potable column, and which can thus realize a large moving amount without increasing the weight thereof. The movement mechanism has a slender moving member, a driving portion for moving the moving member, a plurality of centering members each having a through hole for the moving member at the center thereof, connected to each other and are moved in linkage with the movement of the moving member so that the distance between the respective centering members can be changed, and a movement passage for supporting and guiding the movement of the centering members.
