A movable armrest provides the movement and rotation of the armrest in various directions during the manipulation of the joystick by an operator. The movable armrest includes: an armrest configured to support operator's arm during the manipulation of a joystick; a housing configured to accommodate the armrest; four helical springs configured to connect between the armrest and the housing; and one or more ball transfer units configured to reduce a friction between the armrest and the housing to function to provide a smooth movement of the armrest. The armrest can move in parallel with the ground surface or rotate about an axis perpendicular to the around surface on the housing in response to a change in the position of the operator's arm. When the operator puts away his or her arm from the armrest, the armrest can return to a default position where the tensions of the helical springs form a balance by means of the helical springs.
