とする可変容量ウオータポンプ。[Claims for Utility Model Registration] A clearance is formed between a boss portion of a main impeller and a boss portion of a sub-impeller, and a vane portion of the main impeller and a vane portion of the sub-impeller, and the main impeller and the sub-impeller are engaged with each other. In a variable capacity water pump that is engaged or disengaged, the main impeller has a larger coefficient of thermal expansion than the sub-impeller, so that when the cooling water is at a high temperature, the clearance is eliminated and the vane portion of the main impeller is mainly engaged. A variable displacement water pump characterized in that power from the main impeller is transmitted to the sub-impeller by contact between the vane portion of the sub-impeller and the sub-impeller.
