A parallel link mechanism (1) for which a base-end link hub (2) is linked to a tip-end link hub (3) via three or more sets of link mechanisms (4) such that the orientation of the tip-end link hub (3) can be changed with respect to the base-end link hub (2). Each link mechanism (4) comprises a base-end and a tip-end link member (5, 6), and a center link member (7). The end link members (5, 6) have a curved member (30) that is curved at an arbitrary angle, and rotary shaft support members (31) that are affixed to one or both ends of this curved member (30) and support rotary shafts (12, 15, 22, 25) which are rotatably linked to the center link member (7) or the link hubs (2, 3) directly or via a bearing. |
