<p>PROBLEM TO BE SOLVED: To provide an inexpensive steering control device having a decreased number of components and having a water-proof property with enhanced reliability. SOLUTION: A rear wheel steering control device comprises a brushless motor 3, a rear wheel drive shaft 4 which carries out reciprocating motion for steering rear wheels, a motion converting mechanism for converting the rotation of the brushless motor into the reciprocating moition, a rotational position sensor 2 which delivers a signal for switching the magnetic pole of the brushless motor 3, and a sensor for detecting a neutral position of the rear wheel drive shaft, and the neutral position detecting sensor is provided on a substrate 2a in the rotational position sensor. With this arrangement, a power source and a ground line may commonly be used by the rotational position sensor and the neutral position detecting sensor.</p> |
