A replaceable shock-proof corner wheel of a trunk includes a base, a frame seat, and an elastomer. The base is fixed at corners of a bottom of a trunk body and has a receiving groove. The frame seat is externally combined to the base and has a wheel hole communicated with the receiving groove. The wheel seat includes a wheel cover, a roller, and an elastomer and is received in the receiving groove of the base. The wheel cover is combined to the base by the covering of the frame seat and thus is confined therein. The roller is pivotally installed in the wheel cover and part of the roller protrudes out from the wheel hole of the frame seat. The elastomer is installed at a top surface of the wheel cover and is clamped between the wheel cover and the wall of the receiving groove so that the wheel seat has a buffer shock-proof elasticity with respect to the base. Thereby, the trunk can be pulled steadier and comfortably without any noise. The safety of the contents in the trunk will not be affected and the corner wheels are retained in a steady condition. Moreover, the present invention can be detached and assembly rapidly so that the destroyed corner wheels can be maintained and updated rapidly.
