PURPOSE: An apparatus for supporting an impeller of a water gauge is provided to resolve abrasion and melting of components by supporting a rotation shaft of an impeller which rotates at a high speed with a back bane assembly formed of metal having a high strength and supporting a part closely connected with the rotation shaft with a ceramic plate having a low thermal conductance and a high strength. CONSTITUTION: An apparatus for supporting an impeller of a water gauge includes a back vane assembly(50) having a back vane spot(40) for supporting the impeller mounted in a housing(11) of water supply pipe at a rear end part, and formed of a metal material for fixing a rotation shaft(31) of the impeller, a circular ceramic plate(52) inserted in an inner coupling groove of the back vane assembly and connecting an end part of the rotation shaft of the impeller.
