A stroller includes a main frame, a backrest, a backrest adjustor, and a linkage device. There is a guide rail formed inside the backrest adjustor. A positioning part of the backrest engages with the guide rail. When a handle of the linkage device is moved upward, a connecting component of the linkage device drives a pushing component of the linkage device to move upward along a supporting rod of the backrest. Accordingly, a protruding portion of the pushing component drives the backrest adjustor to rotate relative to a supporting frame of the main frame so as to release the positioning part from the guide rail.
