ABSTRACT:
A steering mechanism for a use in a conveying and hoisting wheel vehicle having at least one steered vehicle wheel, comprises: a steering shaft; a first wheel rotatably driven by the steering shaft; a second wheel pivoting and steering the steered vehicle wheel and having a center axis of rotation extending on the equatorial plane of the steered vehicle wheel; torque transmitting means passed between the first and second wheels, the torque transmitting means having a travelling path having a meeting point at which the torque transmitting means is brought into tangential engagement with the second wheel and a parting point at which the torque transmitting means is brought out of engagement with the second wheel, the travelling path having a semi-circular turning portion at which the torque transmitting means is engaged with the circumferential section of the second wheel. The second wheel is formed to have such a circumference that the length between the center axis of rotation of the second wheel and any one of the meeting and parting points of the travelling path of the torque transmitting means is smaller than the length between the center axis of rotation of the second wheel and an arbitrary point on the semi-circular circumferential section of the second wheel in the state that the steered vehicle wheel assumes a straight movement position.
