PROBLEM TO BE SOLVED: To inhibit the poor appearance of a tire by raising the stiffness to the bending deformation of a serial plate for a distinguishing engraved marker of a tire and preventing the plate from being bent when vulcanizing molding. SOLUTION: Protrusion rows 4 projecting in the shape of a cross section of a V shape are formed along the longitudinal direction in the vicinity of both ends in the direction intersecting perpendicularly with the longitudinal direction that is a portion on which a distinguishing marker 3 of serial plate 1 is not marked. The protrusion rows 4 raise the stiffness to bending of the serial plate 1 so as to prevent the plate from being bent even if receiving bending stress from a green tire expanding within a mold when vulcanizing molding.
