摘要
A production method for a supporting member without a joint, a supporting member without a joint, and a pneumatic run flat tire comprising the supporting member are obtained. The shell without a joint can be obtained by shaping a cylindrical member having a bottom part out of a metal plate by the deep drawing process, removing an opening part side and the bottom part side of the cylindrical member, and curving the cylindrical member into a shape comprising a convex part at the axial direction middle part of the cylindrical member projecting to the outside in the radial direction.
