An interlocking method and its structure for wheel-rim cover is provided and includes a plurality of engaging seats integrally formed along the peripheral edge of the rear side of a wheel-rim cover body. Each engaging seat has an interlocking block pivotally coupled thereto. An inner edge of the interlocking block forms the pivotal axis thereof and is displaceably disposed on an inclined surface of an engaging slot formed in the engaging seat. The outer edge of the interlocking block is displaceably disposed in an engaging groove of the wheel-rim body. By that arrangement, displacement of the wheel-rim cover body toward the hub of the wheel-rim body results in a displacement of the interlocking block to provide respective frictional engagement of the inner and outer ends of the interlocking block with the inclined surface of the engaging slot and the surface of the engaging groove.
