装置。[Claims for Utility Model Registration] A voltage dividing resistor whose one end is connected to a power source and the other end is grounded is formed in a predetermined angular range on the same circumference, and is connected to the steering shaft while slidingly contacting the resistor. A pair of contacts rotating on the same circumference as the resistor are provided facing each other around the center of the circumference, and when one of the pair of contacts is located on a non-forming part of the resistor, the other contact is located on the same circumference as the resistor. In a vehicle steering angle detection device configured to be located on a resistor and detect a steering angle by obtaining a divided voltage output from at least one of a pair of contacts, A conductor is provided in the same angular range as the forming angle range of the resistor, and a switch contact is provided that rotates together with the pair of contacts while slidingly contacting the conductor at the same angular position as one of the pair of contacts. , detecting the non-formed portion of the resistor based on contact/non-contact between the conductor and the switch contact to determine the angle of the non-formed portion, and detecting the steering angle based on the angle of the non-formed portion. A steering angle detection device for a vehicle, characterized in that the device is configured to
