Zusammenfassung:PURPOSE:To provide an electrically driven pump in which a constant circulating flow amount is maintained at all times without being influenced by a pressure used in a pump, and noise generated by water flow is reduced and high efficiency, a long life, high reliability can be provided without having any dangerous property for increasing a temperature abnormally. CONSTITUTION:A radial direction hole 30 for communicating the hole 14A in the axial direction of a motor shaft 14 with a pump chamber 24, is provided in the motor shaft 14 positioned in the vicinity of a passage for leading cooling water from the pump chamber 24 into a motor, and the pump side top end part of the hole 14A in axial direction is sealed in blind condition.
