CONSTITUTION: An impeller(30) comprises a first stage impeller(31), a second stage impeller(35) and a coupling member(40). The first stage impeller includes a first stage blade(32) for applying a centrifugal force to the water coolant; and a plurality of accommodation grooves formed along the outer periphery of a shaft hole so as to accommodate the coupling member to be coupled with the second stage impeller when the water coolant has a high temperature. The first stage impeller is inserted to an end of a rotating shaft(22) so that the first stage impeller rotates together with the rotating shaft. The second stage impeller includes a second stage blade(36) having an outer diameter larger than the outer diameter of the first stage impeller, and which applies a centrifugal force to the water coolant; and a plurality of coupling holes formed along the outer periphery of a shaft hole such that the coupling holes are symmetrical to the accommodation grooves formed at the shaft hole of the first impeller. The second stage impeller is coupled to the rotating shaft. The coupling member operates to transfer the rotating force of the first stage impeller to the second stage impeller when the temperature of water coolant rises due to the high speed rotation of engine.
