PROBLEM TO BE SOLVED: To so set the number of spherical bearings which are used as to be two.SOLUTION: A four degree-of-freedom mechanism comprises: a three degree-of-freedom planar surface closed link mechanism 11 in which a movable surface 112 is movable at three degree-of-freedom in a planar surface with respect to a stationery surface 111; an actuator 12 which is attached to the stationery surface 111 and directly acts in a direction perpendicular to the planar surface; a spherical bearing 13a of which one end is connected to an output shaft of the actuator 12; a spherical bearing 13b of which one end is connected to the other end of the spherical bearing 13a; and an output surface 14 which moves in linkage with the movable surface 112 in a face parallel to the movable surface 112, and is directly or indirectly connected to the other end of the spherical bearing 13b with the movable surface 112 interposed therebetween.SELECTED DRAWING: Figure 1 【課題】使用する球面軸受けの数を２つとする。【解決手段】可動面１１２が固定面１１１に対して平面内において３自由度で移動可能な３自由度平面閉リンク機構１１と、固定面１１１に取付けられ、平面に垂直な方向に直動するアクチュエータ１２と、一端がアクチュエータ１２の出力軸に接続された球面軸受け１３ａと、一端が球面軸受け１３ａの他端に接続された球面軸受け１３ｂと、可動面１１２に平行な面内で当該可動面１１２に連動して移動し、当該可動面１１２を挟んで球面軸受け１３ｂの他端に直接又は間接的に接続された出力面１４とを備えた。【選択図】図１
