A stroller includes a chassis, a main body disposed on the chassis, and a first vibration-absorbing mechanism including a first rod structure, a first sleeve structure, a first inner elastic part, and a first outer elastic part. The first rod structure is connected to a side of the chassis. The first sleeve structure is connected to the main body and movably sleeves the first rod structure. The first inner elastic part abuts against the first rod structure and the first sleeve structure. When the first vibration-absorbing mechanism is in a first use state, the first outer elastic part is in contact with one of the first sleeve structure and the first rod structure. When the first rod structure slides toward the first sleeve structure over a specific distance, two ends of the first outer elastic part abut against the first sleeve structure and the first rod structure, respectively.
