A second member having a case, a lead arm engaged with the case and a button which operates the lead arm. A third member having a wire in which one end is connected to the taper arm and the other end is connected to the lead arm and a covering member in which one end is connected to the taper holder and the other end is connected to the case so that the wire is slidable in the covering member and the opening/closing pin is pushed by an operation of the taper arm which is engaged with the wire when the lead arm is operated by the button.

The height of a chair is adjusted easily and conveniently as the button is installed in the arm resting member of a chair.
