A vehicle includes running wheels traveling on traveling road surfaces of tracks; a pair of position detection parts disposed at an interval in a width direction that output signals by detecting a distance from measured objects; a control unit controlling the amount of steering of the running wheels according to the signals from the position detection parts; and a steering mechanism steering the running wheels via the control unit. Each of the position detection parts outputs a signal having characteristics such that the output increases as the distance from the measured objects increases while an output change ratio is decreased in a range wherein the distance from the measured objects is not less than a predetermined value, and is configured such that, when the distance between one position detection part and the measured object is decreased, the distance between the other position detection part and the measured object is increased.
