Abstract
In this parallel link mechanism, a distal end side link hub is coupled to a proximal end side link hub via three or more link mechanisms such that the posture of the distal end side link hub can be altered relative to the proximal end side link hub. Each link mechanism includes proximal side and distal side end link members and an intermediate link member. Each end link member includes: a curved member curved by an arbitrary angle; and a rotation shaft support member fixed to one end of or each of opposite ends of the curved member, and configured to support a rotation shaft rotatably coupled directly or via a bearing to the intermediate link member or the link hub.
