TUBULAR MOVABLE BODY

摘要

PROBLEM TO BE SOLVED: To provide a tubular movable body capable of restricting reduction in moving speed.SOLUTION: This invention relates to a tubular movable body comprising: a plurality of telescopic constituting members composed of tubular bodies that can be extended or retracted along a central axis; and a connecting part connecting an end part of one of telescopic constituting members adjoining to each other with one end of the other opposing telescopic constituting member. The tubular movable body can be moved by extending or retracting the telescopic constituting members. The connecting part (unit connecting body) does not extend or retract in an extending direction of the connecting part along the central axis of the tubular movable body and when an external force is applied thereto, the extending direction of the connecting part can be changed through its bending and at the same time when the external force bending the connecting part is not applied to the connecting part, it is recovered from the bent state.SELECTED DRAWING: Figure 8
