Claims

[Claims for Utility Model Registration] A plurality of sets of inner and outer tubes 2 and 3 that are arranged concentrically and are expandable and retractable in the axial direction, and at least one set of inner and outer tubes 2 and 3.
and a fixing device 4 for preventing expansion and contraction of the inner and outer tubes 2 arranged in parallel between mutually opposing side walls.
. It consists of a member 14 and a fitted member 15 that is externally fitted onto the inner tube 2 so as to be movable in the axial direction, and the fitted member 1
4 has a tapered part 16 having a small diameter tip formed on the outer periphery, and the fitted member 15 has a tapered hole 17 and a cylindrical part supported by the inner tube 2 and concentric with the inner tube 2 at the small diameter end side of the tapered hole 17. A shaped support surface 18 is formed, the tapered hole 17 is arranged opposite to the tapered part 16, and the axis of either the tapered part 16 or the tapered hole 17 is aligned with the axis of the cylindrical support surface 18. A strut characterized in that at least one of the inner and outer tubes 2 and 3 provided with the fixing device 4 is provided with a pressing device 5 that is not on the same line as the center and applies a pressing force in an axial direction thereof. shelf.
