Abstract: A steering limit device includes an external tube and a shaft tube coupled to a handlebar and a fork of a bicycle respectively. The external tube has a plurality of first rotation limit portions disposed on an inner wall of a predetermined section of the external tube; the shaft tube has a plurality of second rotation limit portions corresponding to the first rotation limit portions respectively formed on an outer wall of the section of the shaft tube being extended into the external tube and a plurality of first pads installed between the first rotation limit portions and the second rotation limit portions, and each first pad limits the relative rotation of the external tube and the shaft tube to achieve the effect of controlling the fork steering effect by the handlebar of the bicycle.
