Claims

[Claims for Utility Model Registration] 1. A bottomed outer cylinder 1 with a telescopic member inside the lower end, an inner cylinder 3 fitted into the outer cylinder 1, and a lifting shaft 6 passing through the inner cylinder 3. Between the lower ends of the lifting shaft 6 directly below the bottom surface of the inner cylinder 3,
A stopper unit 7 that expands outward when pressurized and returns to its original shape when the pressure is released is installed, and the stopper unit 7 is pressurized by lifting only the lifting shaft 6 at a desired height position of the inner cylinder 3. A height adjustable device characterized in that the outer circumferential surface of the device is crimped onto an inner circumferential wall 12 of an outer cylinder 1. 2. The height adjustable device according to claim 1, wherein the stopper unit 7 is a rubber body. i. The height adjustable device according to claim 1, wherein the stopper unit 7 has an outer peripheral surface made of a member with a large friction coefficient and an inner part made of an incompressible member.
