The present invention relates to an armrest apparatus installed in a chair for a computer work. An armrest member which is freely movable on a horizontal surface by a link apparatus is provided in an upper portion of an armrest body vertically installed at both sides of a seat of a chair. The armrest apparatus is used as a common armrest for a chair at a usual time on which a user's arms are placed in such a manner that an armrest member is closely contacted with an upper surface of an armrest body or is lifted upwardly. The armrest member is upwardly lifted at the height at which a keyboard work is conveniently performed during a computer work, so that a user's arms are freely movable on the armrest on a horizontal surface.
