PROBLEM TO BE SOLVED: To prevent the life expectancy of a driving part from shortening due to long-time driving. SOLUTION: In this actuator device 10, a counter value C of a counter is incremented while driving parts 14L and 14R drive by an operation command outputted from an operation switch 70. Therefore, when the driving parts 14L and 14R are driven for a long time, the count value C of the counter has reached a preset upper limit and drives of the driving parts 14L and 14R are forced to stop. Thus, even if each of driving motors 16 of the driving parts 14L and 14R is one of a short-time rating, each driving motor 16 is prevented from being driven continuously. Therefore, for example, it is possible to prevent the driving parts 14L and 14R from generating heat or the like and to prevent the life expectancy of the driving parts 14L and 14R from shortening due to the long-time driving of the driving parts 14L and 14R.
