To provide a vehicular steering device capable of steering two steered wheels by a simple steering mechanism.

Steering shafts 4 are provided on steered wheel supporting frames 3 rotatably journaling the steered wheels 1, and the steering shafts 4 of the steered wheel supporting frames 3 are respectively attached to a vehicle body 5 so as to horizontally rotate. A handle shaft 6 provided on a handle bar 2 is horizontally rotatably attached to the vehicle body 5 at a position between the pair of the steering shafts 4. Wheels 7, 8 are respectively provided to the handle shaft 6 and the steering shafts 4. The wheel 7 of the handle shaft 6 and the wheels 8 of the steering shafts 4 are coupled by a power transmitting cable element 9, and the steering shafts are horizontally rotated by following horizontal rotations of the handle shaft 6. The handle shaft 6 is rotated by rotating the handle bar 2, thereby rotating the pair of the steering shafts 4 coupled to the handle shaft 6 through the wheels 7, 8 and the power transmitting cable element 9 in the same direction. Therefore, the pair of steering wheels 1 can be rotated.
