Abstract: A vehicle advances forward while turning to the right when an operating lever is tilted forward and to the right, that is, being operated in a direction intermediate between the forward direction and right-hand direction. Only an output signal of the component corresponding to the forward direction is preserved when the operating lever is released. The component corresponding to the right-hand direction returns to the neutral position, and the signal output is brought to zero. The vehicle therefore moves only forward. The operating position can thus be preserved and a signal output state can be held for a single directional component selected from longitudinal and transverse direction components when operating the operating lever device which is tilted along the directional components in both longitudinal and transverse directions.
