Abstract
A cooling device having a centrifugal pump directly mounted on a radiator. An annular seal member is disposed between the bottom portion of the case body of the centrifugal pump and the side surface of the tank chamber of the radiator, and the annular seal member is used for preventing the cooling medium leakage via a space between the centrifugal pump and the tank chamber. The cylindrical portion of the case body and the annular seal member are overlapped with each other in the axial direction of the rotation center shaft of the motor that drives the centrifugal pump, in order that the cylindrical portion can receive at least a part of the reaction force of the annular seal member crushed between the case body and the tank chamber, and thereby the bottom portion of the case body of the centrifugal pump is prevented from deformation.
