A combination type link actuation device having two link actuation devices combined with each other, wherein each link actuation device comprises: a proximal end side link hub ; a distal end side link hub ; and three link mechanisms aligned in a circumferential direction, the three link mechanisms connecting the proximal end side link hub with the distal end side link hub such that an orientation of the distal end side link hub is changed relative to the proximal end side link hub , each link mechanism includes: a proximal side end link member having one end that are rotatably connected to the proximal end side link hub ; a distal side end link member having one end rotatably connected to the distal end side link hub ; and an intermediate link member having opposite ends that are rotatably connected to the other ends of the proximal side end link member and the distal side end link member , two or more link mechanisms among the three link mechanisms have an orientation controlling actuator therein, the orientation controlling actuator optionally changing an orientation of the distal end side link hub relative to the proximal end side link hub , and at least one separation angle (δ1) among the three separation angles (δ1, δ2, δ3), in the circumferential direction, of the three link mechanisms is greater than 120°, and the respective link mechanisms with the separation angle (δ1) greater than 120° in the two link actuation devices are disposed to confront with each other, wherein the proximal end side link hub and the distal end side link hub have a U-shape which is opened on a side where the separation angle (δ1) is greater than 120°, as viewed in a direction perpendicular to a plane on which the proximal side and distal side end link members of the three link mechanisms are aligned. each link actuation device comprises: a proximal end side link hub ; a distal end side link hub ; and three link mechanisms aligned in a circumferential direction, the three link mechanisms connecting the proximal end side link hub with the distal end side link hub such that an orientation of the distal end side link hub is changed relative to the proximal end side link hub , each link mechanism includes: a proximal side end link member having one end that are rotatably connected to the proximal end side link hub ; a distal side end link member having one end rotatably connected to the distal end side link hub ; and an intermediate link member having opposite ends that are rotatably connected to the other ends of the proximal side end link member and the distal side end link member , two or more link mechanisms among the three link mechanisms have an orientation controlling actuator therein, the orientation controlling actuator optionally changing an orientation of the distal end side link hub relative to the proximal end side link hub , and at least one separation angle (δ1) among the three separation angles (δ1, δ2, δ3), in the circumferential direction, of the three link mechanisms is greater than 120°, and the respective link mechanisms with the separation angle (δ1) greater than 120° in the two link actuation devices are disposed to confront with each other, wherein the proximal end side link hub and the distal end side link hub have a U-shape which is opened on a side where the separation angle (δ1) is greater than 120°, as viewed in a direction perpendicular to a plane on which the proximal side and distal side end link members of the three link mechanisms are aligned. <EOS>
