An operating knob device has: a position detection portion for detecting a position of a set numerical value of an object to be set; an operating portion for changing and operating the set numerical value; a drive portion for driving the operating portion; and a control portion for controlling the drive portion on the basis of a detection result of the position detection portion. The control portion includes: a first position calculation portion for calculating a first set numerical value that is a current set numerical value of the object to be set, on the basis of the detection result of the position detection portion; a second position calculation portion for calculating one or a plurality of second set numerical values that are set numerical values before change of the object to be set, on the basis of the detection result of the position detection portion; and a drive control portion for controlling the drive portion to be driven and changing and controlling a drive parameter of the drive portion when an absolute value of a difference between the first set numerical value and at least one of second set numerical values falls within an allowable range. Thus, the operator may reset the position of the operating portion only in accordance with a finger feel without visually confirming the position.
