Contributions of the direct quark mechanism are studied in the non-mesonic weak decays of light hypernuclei. The AN --~ NN transition is described by the one pion exchange mechanism and the direct quark mechanism, induced by the four-quark vertices in the effective weak Hamiitonian. By employing a r
