A wheel assembly for a trunk-attached carriage includes an integrally formed wheel bracket having a vertical, a side and a bottom plate for mounting onto a lower rear corner of a trunk, a compression spring, a short wheel axle, a locking member, and a wheel. The wheel bracket defines a wheel-space for the wheel to locate therein. The wheel axle transversely extends across behind the vertical plate of the wheel bracket to pass through an axle hole on the wheel, so that the wheel is rotatably mounted on the wheel axle and connected the wheel bracket. An end of the wheel axle close to the side plate of the wheel bracket is connected to a diameter-reduced inner end of the locking member, so that the wheel axle can be turned into a locked position on the wheel bracket by turning a diameter-expanded outer end of the locking member. And, by turning the locking member in a reverse direction, the wheel axle can be removed from the wheel bracket for replacement of any damaged component of the wheel assembly.
