For providing in an operating device capable to be operated as the operator intended, an operating device has a joystick and guide member. The joystick is provided with a support portion supporting an operating shaft to swivel freely in omni-directions, and sensing switches. The sensing switches detect that the operating shaft swivels and one end thereof goes into a detecting area. A boundary is provided between the detecting areas of the neighboring sensing switches. The guide member has a through hole for passing the operating shaft. An inner edge of the through hole is formed alternately with a convex portion and a concave portion.
