Abstract
In a parallel link mechanism, a distal end side link hub is coupled to a proximal end side link hub via three link mechanisms such that a posture of the distal end side link hub can be changed relative to the proximal end side link hub. Each link mechanism includes a proximal side end link member rotatably coupled at one end thereof to the proximal end side link hub, a distal side end link member rotatably coupled at one end thereof to the distal end side link hub, and a center link member rotatably coupled at both ends thereof to other ends of the proximal and distal side end link members via both revolute pair sections. The parallel link mechanism includes a rotation transmission mechanism configured to allow rotation of one revolute pair section to rotate the other revolute pair section in reverse.
