ABSTRACT:
A reinforced structure for the joints of the braces on a baby stroller, and especially an improvement of the first and second joints each constructed by a front brace and the rear brace respectively with a corresponding handle. The first joints have engaging ends of predetermined length, the second joints have grooves for receiving the engaging ends. When the baby stroller is unfolded completely, the engaging ends are engaged in the grooves. Stress on the baby stroller can be transferred to the whole structure of the baby stroller rather than concentrated on the first joints. Useful life of the baby stroller can thus be prolonged. A locking device is provided on the first or second joints.
