PROBLEM TO BE SOLVED: To provide a vehicular steering device that can take a large maximum steering angle while securing steering stability at the time of normal traveling. SOLUTION: The vehicular steering device comprises; a knuckle 5, whose upper support point 7a and lower one are supported on a vehicle body via suspension members (a sub-link 10 and an upper arm 11) and whose upper support point 7a is arranged inside the inside surface 16 in the vehicle width direction of a wheel 1; a king pin shaft changing device, which has two degrees of freedom of a first degree of freedom of changing a king pin offset amount and a second degree of freedom of changing a king pin tilt angle and which can move between inside and outside positions from the side surface 16 of the lower support point; a steering control device 19, which controls the steering angle of the wheel 1 based on a target steering angleθaccording to a steering state; and a king pin shaft control device 20, which controls the king pin shaft changing device according to the target steering angleθ.
