<p>PROBLEM TO BE SOLVED: To enable plural kinds of rotation patterns, and to increase rotational force, in a rotating member rotated by the traction of a fluid pressure type actuator.SOLUTION: In a rotation device 1, a first actuator 10 and a second actuator 20 are disposed on a base member 2 rotatably coupled with a rotating member 6. Rotating directions of the rotating member 6 by the traction of both actuators 10 and 20 are made to be same. The supply of fluid is switched between a system for supplying to the first actuator 10 and then supplying to the second actuator 20, a system for simultaneously supplying both actuators 10 and 20, and a system for supplying to the second actuator 20 and then supplying to the first actuator 10. Therefore, plural kinds of rotation patterns of the rotating member 6 can be obtained, and rotational force can be increased while both actuators 10 and 20 are actuated.</p> |
