ABSTRACT:
An arm support of a chair which is adjustable to set a height of the armrest and a distance between the armrests includes a support pole, a jacket, a fixed jacket and two toothed members. Each toothed member is provided with teeth along one side thereof. The support pole which is L-shaped has a vertical part and a horizontal part which are formed respectively with an oblong orifice. The jacket has an interior spacing for receiving the vertical part of the support pole. The first toothed member is fixed inside the oblong orifice of the vertical part of the support pole. The jacket is engaged with an elastic button. When a user wants to adjust the arm support to set the height of the armrest, the user may press the elastic button to raise or lower down the jacket with respect to the support pole so as to adjust the height of the armrest. The fixed jacket is fixed on the chair and has an interior spacing for receiving the horizontal part of the support pole. The second toothed member is fixed inside the oblong orifice of the horizontal part of the support pole. The fixed jacket is engaged with an expanded end member. When a user wants to adjust the arm support to set the distance between the armrests, the user may rotate the expanded end member to adjust the position of the support pole relative to the chair and thus the distance between the armrests.
