とするウオータポンプ。 A mechanical seal is provided between the bearing and an impeller fixed to one end of a rotating shaft supported by a body via a bearing, and a space between the mechanical seal and the bearing and a drive for driving the rotating shaft. In a water pump in which a discharge passage is formed which communicates with an inner closed part of a pulley, a protrusion is formed on an end opening of the discharge passage to the inner closed part of the drive pulley on a lagging side in the rotational direction of the drive pulley. A water pump characterized by:
