Claims

[Scope of utility model registration request]

Two magnetic detection units 3 and 4 arranged to cross each other
and a magnetic sensor 6 disposed under the geomagnetic action on the vehicle 5, and detects the vehicle direction with respect to the geomagnetic direction from two detection outputs from the magnetic sensor 6, wherein the magnetic sensor Reference numeral 6 denotes a vehicle direction detection device, characterized in that its reference axis 61 is set in a positional relationship that substantially coincides with the maximum direction B of the magnetic induction tendency of the vehicle 5.
