A mobile vehicle provided with moving means and a moving control device automatically travels while detecting an advance distance and a turning angle by means of one optical displacement sensor. The mobile vehicle comprises a moving unit () for moving a body (), one optical displacement sensor () as a displacement sensor provided on the body (), and a moving control device for controlling the moving unit () based on a moving distance detected by the optical displacement sensor (). The moving control device determines the distance of rectilinear movement and a turning angle of the body () from an amount detected by the optical displacement sensor (). The optical displacement sensor () picks up patterns or the like on a traveling floor surface at specified time intervals and detects a moving distance by comparing images before and after the specified time.
