1. A steering device for a vehicle, comprising:
an operation member configured to be operated by a driver;
a turning member mechanically separated from the operation member and configured to turn a wheel;
a turning device configured to drive the turning member; and
a controller configured to control the turning device,
wherein the controller has:
a first control mode in which a maximum turning angle of the wheel is set to a first angle corresponding to a maximum angle for mechanically turning the wheel; and
a second control mode in which the maximum turning angle of the wheel is set to a second angle that is smaller than the first angle; and
the controller is configured to switch between the first control mode and the second control mode based on a current travel condition of an own vehicle detected by a travel condition detecting unit,
wherein in the travel condition corresponding to the first control mode, the controller sets the maximum turning angle to the first angle that has been corrected to decrease by a prescribed value in response to detecting that the wheel moves onto a step,
wherein in a case where the controller transitions from the first control mode to the second control mode in response to detecting an actual turning angle of the wheel between the first angle and the second angle, the controller forcibly changes the actual turning angle of the wheel to the second angle.
