A water pump includes a pump body and a pump cover. An impeller is housed in a pump chamber defined by the pump body and pump cover. The impeller is attached to one end of a hollow pump shaft. The pump shaft is engaged with a driving section at its other end. An intermediate part of the pump shaft is supported by a shaft support section, in the form of a cylindrical section, of the pump body. The shaft support section is longer than a diameter of the pump shaft. The shaft support section is lubricated via an oil groove. One end of the shaft support section is brought into contact with a flange of the pump shaft via a washer. The flange is integrally formed on the pump shaft by a beading process.
