A yoke structure of a steering device is provided to increase a support power of a rack bar when a steering handle is positioned in a middle point, thereby reducing a shimmy phenomenon, and to weaken the support power of the rack bar when the steering handle moves leftward or rightward, thereby enhancing the stability of the rack bar. A yoke structure of a steering device includes a yoke body(12a), a support spring, and a support power changing unit. The yoke body supports a rack bar by making contact with the rack bar toothed with a pinion gear coupled to a steering handle such that the pinion gear cooperates with the steering handle. The support spring elastically supports the yoke body. The support power changing unit changes support power when the steering handle is positioned at a middle point or moves leftward or rightward.
