  • Patent number: 5056787
    Abstract: A steering apparatus for a game machine according to the invention has a mechanism in which a steering wheel is rotated in accordance with the steering operation of the player and is automatically returned to the center. An end cam which always receives the elastic force of a compression coil spring sets the steering wheel to the neutral position, namely, the center by way of a guide roller. For instance, when the player operates the steering wheel to the right rotational direction, the guide roller rotates to the right together with the steering shaft. Thus, the end cam moves along the axial direction of the steering shaft in accordance with a rotational angle of the steering wheel. Then, when the steering wheel is released, the end cam receives the elastic force of the compression coil spring and allows the steering wheel to be returned to the center by way of the guide roller without performing the reversing operation of the steering wheel.
