PROBLEM TO BE SOLVED: To enable plural types of turning patterns and increase turning force for a turning member turned by traction of a fluid-pressure type actuator. SOLUTION: In a turning device 1, a first actuator 10 and a second actuator 20 are arranged on a base member 2 to which the turning member 6 is turnably connected, and respective turning directions of the turning member 6 by the traction of the both actuators 10, 20 are the same each other. A supply method of fluid can be switched to a type for supplying the fluid to the first actuator 10 first and then to the second actuator 20, a type for supplying the fluid to the both actuators 10, 20 at the same time, and a type for supplying the fluid to the second actuator 20 first and then to the first actuator 10. Thus the plural types of the turning patters can be enabled for the turning member 6, and the turning force can be increased when the both actuators 10, 20 are under operation.
