PROBLEM TO BE SOLVED: To provide a link operating device provided with a link mechanism having high rigidity and large portable weight with a compact constitution. SOLUTION: This device has three pairs of link mechanisms 1 to 3 for rotatably connecting end part link members 1a to 3a and 1c to 3c to link hubs 4 and 5 provided on each of an input member 6 and an output member 7 and for rotatably connecting the end part link members 1a to 3a and 1c to 3c of each of an input side and an output side to center link members 1b to 3b. The input side and the output side are made geometrically the same in cross section at a center part of each link mechanisms 1 to 3. Resting mechanisms 11 for resting the output member 7 at an arbitrary position are provided in rotation parts in the rotation pairs of two pairs of link mechanisms 1 to 3 of the rotation pairs of each link mechanism 1 to 3 connected to the input member 6.
