摘要

A positioning device is adapted to position a rear frame of a foldable bicycle relative to a front frame when the foldable bicycle is folded, and includes a rear anchoring member and a front anchored member adapted to be secured to rear and front wheel axles of the foldable bicycle and outboard to rear and front wheels, respectively. The rear anchoring member includes an outer lateral wall with upper and lower guiding surfaces, and a circumferential wall which extends from the outer lateral wall and which defines an insert slot extending rearwardly to form a first abutment wall. The front anchored member includes an inserted outer annular portion insertable into the insert slot, and a guided annular portion extending from an inner periphery of the inserted outer annular portion and having upper and lower contact parts so as to slidably engage the upper and lower guiding surfaces when the inserted outer annular portion is inserted into the insert slot. Thus, the front anchored member is retained on the rear anchoring member so as to position the rear frame relative to the front frame of the foldable bicycle.
