A vehicle steering device includes: a steering mechanism 30 that steers steered wheels 4 by driving of a steering motor 34 according to operation of an operation unit; a motor angle sensor 36 that detects a rotation angle of the steering motor 34 as an electrical angle; a steered angle sensor 42 that detects a steered angle of the steered wheels 4; a storage unit in which correspondence between the electrical angle and the steered angle that are detected is stored in advance; and a failure determination unit that determines whether there is a failure or not by comparing the relation between the detected electrical angle and the detected steered angle with the correspondence between the electrical angle and the steered angle that is stored in the storage unit.
