Adherence between a cord end portion and peripheral rubber becomes good. Accordingly, stiffness change between the the end portion of the bead reinforcing cord and the peripheral rubber positioned on an extension line of the end portion becomes smooth, and the occurrence of a separation phenomenon in a bead portion is suppressed.  <P>COPYRIGHT: (C)2004,JPO
