Abstract: A bearing is interposed in the revolute pair between a proximal end side link hub and each proximal side end link member. A control device controls an actuator, to perform work-time control for causing a determined work operation to be executed and to perform, while the work-time control is stopped, grease circulation control for circulating grease sealed in the bearing.
