The pump shaft is provided with a mechanical seal consisting of a rotating member attached to the pump shaft and a fixed member attached to the housing, and the pump shaft has a waterproof flange extending radially outward through between the rolling bearing and the mechanical seal. In a water pump that is installed in a fixed manner, a non-contact seal is provided between the rotating part and the stationary part to prevent foreign matter from entering between the fixed member of the mechanical seal and the pump shaft. pump.
