According to the present invention, a device for three-dimensional motion of lumber joints includes a driving module which makes three-dimensional motions of human lumber joints possible; a housing which accommodates the driving module therein; and a mount part which is joined with the driving module and is arranged on an upper part of the housing. The driving module includes a height adjusting part of which the top is joined with the mount part; a connecting rod which is joined with the height adjusting part and has the adjustable length; a joining structure which is joined with the connecting rod to be able to rotate; and a rotation axis structure which provides rotational force to the joining structure while being joined with the joining structure. According to the present invention, the connecting rod joining structure, which can move three-dimensionally and can slide by the driving module having three hinge joints, is used so as to actively adjust a radius of rotation of the connecting rod. |
