A driving operation device includes an input portion, an output portion and a form modifying portion that transmits an amount of operation of the input portion to the output portion. The form modifying portion can modify an orientation of the input portion depending on a position of the output portion. This can maintain the input portion vertical or horizontal, for example. The form modifying portion also can modify a ratio of an amount of operation of the input portion to an amount of change in the output result based upon the position of the output portion.
