A link drive structure (10) includes a first arm (11) constituting a parallel link on one side, a second arm (12) constituting a parallel link on the other side, a coupling base (3) interposed between end portions, at which the first arm (11) is coupled with the second arm (12), to couple the end portions of both the parallel links, and a drive motor (50) with a harmonic gear reducer (30) disposed to the coupling end portion of the arm (11) on the one side. The harmonic gear reducer (30) has two output shafts (37,38) rotating in the same direction, a first output shaft (37) is coupled with the end portion of the other arm (12), and a second output shaft (38) is coupled with the coupling base (3). With this arrangement, there can be provided a link drive structure having a high positioning accuracy and an excellent sealing property and an industrial robot using the link drive structure. |
