A parallel link mechanism (1) is configured by connecting a front end-side link hub (3) to a base end-side link hub (2) through three or more sets of link mechanisms (4) so that the attitude of the front end-side link hub (3) is changeable. Each of the link mechanisms (4) comprises: a base end-side end link member (5) having one end rotatably connected to the base end-side link hub (2); a front end-side end link member (6) having one end rotatably connected to the front end-side link hub (3); and a center link member (7) having opposite ends rotatably connected to the other ends, respectively, of the base end-side and front end-side end link members (5, 6). The center link member (7) is provided with a plate material having two or more bends (7a) at which the plate material is bent in the plate thickness direction. |
