摘要： PROBLEM TO BE SOLVED: To provide a steering device that can determine its failure with a simple configuration. SOLUTION: A tire angle control unit 29 of a steering device 10 steers a vehicle by an operation in a main operational direction M, which is a direction toward which a steering wheel 12 is turned, and operations in a sub-operational direction Sb1, which is a direction toward which the steering wheel 12 is inclined, and a sub-operational direction Sb2, which is a direction toward which the steering wheel 12 is pushed or pulled. A failure determining unit 28 determines that the steering device 10 has failed based on a change of an input value by the operation in the main operational direction M and input values by the operations in the sub-operational directions Sb1 and Sb2 and changes thereof. Thereby, the failure can be determined based on the input values of the operation in the two or more operational directions, such as the turning direction and the inclination direction of the steering wheel 12, without equipping functions for determining the failure to the operation system relating to the operation in the main operational direction M and the operation system relating to the operations in the sub-operational directions Sb1 and Sb2, respectively.
