A stroller is convertible between an unfolded state and a folded state, and includes a handle frame (2) disposed pivotally on a wheel frame (1) and pivotable between an inclined position and a horizontal position. A brace member (4) interconnects the handle frame (2) and the wheel frame (1), and is convertible between a supporting state, where the handle frame (2) is disposed at the inclined position and where the stroller is in the unfolded state, and a non-supporting state, where the handle frame (2) is disposed at the horizontal position and is folded on the wheel frame (1) and where the stroller is in the folded state. A retaining unit (6) maintains the stroller in the folded state, and allows for a one-touch operation so as to permit the handle member (2) to be biased by a biasing unit to the inclined position. The biasing unit comprises a gas spring (52) and a torsion spring (51). |
