Abstract:

Provided is a link actuation device (51A) that connects a tip-side link hub (3) to a base end-side link hub (2) via three or more sets of link mechanisms (4) such that the orientation of the tip-side link hub (3) can be changed. Each link mechanism (4) comprises base end-side and tip-side end link members (5, 6) and a central link member (7). The link mechanism (4) is provided with an actuator (53) that changes the orientation of the tip-side link hub (3) with respect to the base end-side link hub (2) in a discretionary manner. An end effector (61) is installed on the base end-side or tip-side link hub (2, 3) so as to face the inner side of the arrangement of both link hubs (2, 3). The end effector (61) performs work on a workpiece (62) that is an object to be worked on and that is arranged on the link hub (2) side that is the side opposite from the link hub (3) on which the end effector (61) is installed.
