This multi-piece rim structure for a wheel is provided with: a rim base 10; a bead seat ring 20 (ring member) for receiving radial and axial loads from tire bead parts; and a lock ring 30. An annular protrusion 35 of the lock ring 30 is fitted in an annular lock groove 15 of the rim base 10. An undercut 15a is formed on the inner surface of the lock groove 15 of the rim base 10. Buried in the undercut 15a is a sacrificial anticorrosive 80 which contains a metal such as zinc or aluminum having a higher ionization tendency than iron, which is the base material of the rim base 10 and lock ring 30. Corrosion of rim base 10 and lock ring 30 is suppressed by the ionization of the sacrificial anticorrosive 80.
