ABSTRACT:
A stroller is convertible between an unfolded state and a folded state, and includes a handle frame disposed pivotally on a wheel frame and pivotable between an inclined position and a horizontal position. A brace member interconnects the handle frame and the wheel frame, and is convertible between a supporting state, where the handle frame is disposed at the inclined position and where the stroller is in the unfolded state, and a non-supporting state, where the handle frame is disposed at the horizontal position and is folded on the wheel frame and where the stroller is in the folded state. A retaining unit maintains the stroller in the folded state, and allows for a one-touch operation so as to permit the handle member to be biased by a biasing unit to the inclined position.
