초록 ▼

A stroller comprises a wheeled carriage frame, a pair of hollow upwardly inclining rear frame supports mounted to the wheeled carriage frame, and a pair of hollow connecting pieces telescopically connected to the rear frame supports. A substantially U-shaped handle has a pair of arm portions rotatably connected to the connecting pieces. The U-shaped handle can thus be rotated relative to the rear frame supports. The telescopic connection between the connecting pieces and the rear frame supports allow the adjustment of the height of the U-shaped handle. The rear frame supports are movable between two positions on a pair of arm rests of the stroller. Each of the rear frame supports has a movable hook body attached thereto to selectively lock the rear frame support against one of the arm rests at one of the two locking positions. A handle lever, hinged to each of the connecting pieces, is operated to move the movable hook body away from the locking position by means of a transmitting cord interconnecting the handle lever and the movable hook body. The rear frame supports can thus be moved to the other locking position on the arm rests to change the position from which the stroller is pushed.
