A coupling member dismounting method including an inclining step of inclining a coupling member relative to a rotational axis of a drum flange, wherein the coupling member includes a spherical portion mounted to a rear end portion of a rotating force receiving member by a pin penetration. The method also includes a pin urging step of pushing the pin from one end to the other end thereof. The method further includes a pin riding step of making a part of the pin which is further projected at the end by the pin urging step ride on a surface and a coupling member dismounting step of dismounting the coupling member from the drum flange by applying a force to a free end portion of the coupling member toward a fulcrum which is the portion of the pin riding on the surface. |
