PROBLEM TO BE SOLVED: To provide a route guiding device which can comfortably and surely transmit the route to be followed by a user to the user. SOLUTION: Just before a vehicle reaches an intersecting point, a mechanical sound is outputted in the advancing direction of a vehicle as if the sound source of the mechanical sound moves against a user by a sound source moving system utilizing phase. That is, the mechanism sound is outputted as if the sound source of the mechanical sound moves in the direction shown by the arrow 51 when the vehicle takes a left-hand turn, by the arrow 52 when the vehicle goes straight on, or by the arrow 53 when the vehicle takes a right-hand turn. The mechanical sound is not an electronic sound, but a click-clack sound produced by a ratchet, etc. |
