PURPOSE: A pressing wheel for preventing separation is provided to prevent the damages to a joining member due to loads on the pressing wheel as spacing projections are not separated. CONSTITUTION: A pressing wheel(10) for preventing separation comprises a body unit(20) and joining portions(30). A through hole(22) is formed in the center of the body unit, and a connecting pipe(12) passes through the through hole. The joining portions are integrally extended from the body unit, and joining holes correspond to the joining parts of a socket pipe(14). One or more spacing projections(24) protrude toward the center axis of the through hole from the body unit, and the end par of the projection is supported by the outer peripheral surface of the connecting pipe.
