PURPOSE: Provided is a movement system for two degree of freedom which secures the scope of pitch and roll movement in an upper sheet as the length of an actuator in a free way so that it enlarges the scope of application. CONSTITUTION: The movement system for two degree of freedom comprises the parts of: a lower sheet(12) which is played as a base; an upper sheet(10) which is supported by a vertical support bar(14) at the center of the lower sheet with forming a combination part with the vertical support bar in a universal joint structure; the actuator(16,18) which is upwardly slid to a certain angle at both terminals of one side of the lower sheet; and a link(20,22) which combines both edges of the upper sheet and each actuator with forming a spherical structure at both edges.
