Abstract: In a high-mounted double wishbone suspension device, an arm portion extending upward from a knuckle main body portion, through which an axle runs, is provided with a tie rod connection portion. A tie rod for turning a wheel is connected to the tie rod connection portion. The distance between the axle and the tie rod connection portion is increased to effectively suppress knuckle lateral vibration centered on the axle by the tie rod. Therefore, it is possible to reduce road noise without increasing the number of components or the weight. In particular, since the tie rod is connected to a joint provided on a lower face of the tie rod connection portion, it is possible to minimize vertical positional change of the tie rod, while suppressing lateral vibration of the knuckle by raising the position of the tie rod connection portion, whereby the arrangement can be easily applied to a conventional vehicle merely by replacing the knuckle alone.
