VEHICULAR STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To realize efficient steering angle characteristic in any turning direction. SOLUTION: Vehicular steering devices 100 and 101 are provided with a straight support mechanism 300 comprising a wheel support member 110 for rotatably supporting a wheel and a member supported by a car body so as to support a turning support point 110d of the wheel support member structuring a king pin shaft freely to move straight or approximately straight in the car cross direction or in the obliquely back and forth direction in relation to a car body, and a steering mechanism comprising an arm member 200 turnably supported by the car body in one end thereof and turnably supported by the wheel support member outside the turning support point in the car cross direction in the other end thereof and a tie-rod 400 connected to the wheel support member so as to turn the wheel support member around the turning support point with movement of the tie-rod when steering. The arm member moves the turning support point 110d of the wheel support member straight or approximately straight outward in the car cross direction with movement of the tie-rod through the straight support mechanism.
