Abstract
A water pump for feeding water under the action of centrifugal force created by rotation of an impeller disposed within a pump case includes a cooling water discharge port formed at a position offset in the axial direction of the pump from the outer peripheral portion of the impeller. A flow path structure having a projecting portion for guiding cooling water from the outer peripheral portion of the impeller up to the discharge port is intended to provide a flow path structure capable of smoothing the flow of cooling water, thereby increasing the amount of cooling water discharged and improving the pumping performance.
