Abstract

A working device () using a parallel link mechanism includes: a parallel link mechanism () by which end effectors () are supported so as to be changeable in posture; and posture-controlling actuators () which actuate the parallel link mechanism (). In the parallel link mechanism (), a distal-end-side link hub () is connected to a proximal-end-side link hub () via three or more link mechanisms () so as to be changeable in posture of the distal-end-side link hub () relative to the proximal-end-side link hub (). The end effectors () are mounted to the distal-end-side link hub (), and includes one main end effector () which performs a main work on a workpiece () and one or multiple sub end effectors () which perform an auxiliary work on the workpiece ().
