A bead ring winding device forms a bead ring by winding a wire fed to the circumference of a former, which is coupled to, in a removable manner, and supported by a rotation shaft. The bead ring winding device includes a guide and a driving member. The guide guides a bearing so that the bearing can be lifted and lowered. The bearing supports the rotation shaft. The driving member lifts and lowers the bearing along the guide. When the former is replaced with another former of a different diameter, the bearing is lifted or lowered with the driving member so that the upper end of the former is arranged at a fixed position.
