CONSTITUTION: A lightweight disc structure of a vehicle comprises a housing(10), a disc(20), and a distribution unit(30). The housing comprises joining holes(11) inducing a wheel and a hub to be joined into a body. The housing comprises one and more joining holes with a radial shape. The disc comprises coupling holes inducing the housing to be coupled into a body. The disc comprises one and more coupling holes with a radial shape. The distribution unit comprises a radiation device(31) or a radiation grove reinforcing breaking power generated in the outer side of the disc.
