Abstract
Abstract A metal carrier is embedded into trim, for providing proper rigidness in the transverse direction as well as in the longitudinal direction to the strip-like trim formed with rubber or plastics and the like. Transverse slots are formed in the strip-like sheet metal at given intervals in the longitudinal direction and a thin link portion and/or narrow width portion (sectional area in the transverse direction is small) is alternately formed at the top and bottom portions of the transverse slot. When an external force is applied to the metal carrier covered with rubber or plastics, the formed connecting links of the thin link portion and/or narrow width portion at top and bottom are broken, and the metal carrier becomes a continuous zigzag strip.
