<p>A coil spring (62L, 62R) as a suspension spring is interposed between a vehicle body (61) and a knuckle arm (10L, 10R) holding left-hand and right-hand rear wheels (2L, 2R) rotatably, respectively. The left-hand and right-hand arms (10L, 10R) are connected to each other through a rear-wheel steering mechanism (12, 21) to which is connected a spring (17) for urging the left-hand and right-hand wheels (2L, 2R) to be retained in neutral position. The rear wheels are steered in resistance to the urging force of the spring (17) by driving the rear-wheel steering mechanism (12, 21) with a motor (20) or the like. In order to prevent the revolving torque of the coil spring (62L, 62R) from being transferred to the knuckle arms (10L, 10R), a revolving torque absorbing member such as a bearing (81) or a ball joint (88) is interposed, for example, between the coil spring (62L, 62R) and the vehicle body (61) or between the coil spring (62L, 62R) and the knuckle arm (10L, 10R).</p> |
