PURPOSE:To give a feeling not different from that of steering a real automobile by providing reciprocating actuators in two places of the circumference of a crank arm integrally coupled to a steering shaft integrated with a steering wheel, and providing switching valves at both end ports of each reciprocating actuator. CONSTITUTION:A steering shaft 2 integrated with a steering wheel 1 is freely, rotatably, pivotally attached to a base 3, and a crank arm 12 is integrally mounted on the steering shaft 2. Base ends of a centering air cylinder 15 and an action air cylinder 16 are pivotally attached to an air-cylinder pivotally supporting bracket 13 via a pivot 14, and tip ends of the centering air cylinder 15 and the action air cylinder 16 are pivotally attached to the crank arm 12. The air cylinders 15, 16 are expanded or contracted as needed correspondingly to the steering angle of the steering wheel 1, so as to exert the steering wheel with steering reaction, vibration and kickback. |
