PROBLEM TO BE SOLVED: To provide a folding two-wheeler allowing mutual transfer of a using state and a folded state of the two-wheeler by a lever operation in a single operation and allowing miniaturization of the mechanism so as not to impart accidental injury to an operator by the movement.SOLUTION: A front frame 5 and a rear frame 7 are connected by a rachet shaft 20, and an antirotation pin 22 engaged and disengaged with/from the rachet shaft 20 is energized to be engaged with the rachet shaft 20 by an energizing means 24. For instance, the engagement of the antirotation pin 22 with the rachet shaft 20 by the energizing means 24 is secured by oscillation of one direction of a hook lever 40 provided in the rear frame 7 via a cam lever 30 while the antirotation pin 22 is disengaged from the rachet shaft 20 against energizing of the energizing means 24 by oscillation of the other direction. |
