  "textContent": "A multi-piece rim structure for a wheel includes a rim base , a bead seat ring (ring member) and a lock ring . The bead seat ring receives a load in a radial direction and an axial direction from a bead portion of a tire. An annular ridge of the lock ring can be received in an annular lock ring groove of the rim base . A receiving groove is formed in an inner surface of the lock ring groove of the rim base . A sacrificial anticorrosion material is embedded in the receiving groove . The sacrificial anticorrosion material includes metal such as zinc and aluminum that has a greater ionization tendency than iron that is a base material of the rim base and the lock ring . Corrosion of the rim base and the lock ring can be suppressed by ionization of the sacrificial anticorrosion material",
