In a link actuating device, a distal end side link hub is coupled to a proximal end side link hub via three or more link mechanisms. A posture control drive source configured to arbitrarily change the posture of the distal end side link hub is provided to each of two or more link mechanisms. The link actuating device includes a storage unit configured to store therein an operating position of the posture control drive source when the distal end side link hub is in a defined posture. In each of the two or more link mechanisms, a positioning portion is provided to at least one of the proximal side end link member, the distal side end link member, and the intermediate link member. A positioning member configured to position the distal end side link hub in the defined posture is dismountably mounted between a plurality of the positioning portions.
