Claims

[Scope of utility model registration request]

A pump housing with a pump chamber inside, a rotating shaft rotatably supported via a bearing by an annular bearing provided in the pump housing, and a rotating shaft mounted in the pump chamber on one end side of the rotating shaft. with the vane
The vane includes a mechanical seal disposed in a space surrounded by the rotating shaft and the bearing section, and the mechanical seal is provided between the pump housing and the vane, and the mechanical seal is provided between the pump housing and the vane. a generally annular seal ring that provides a watertight seal between the pump chamber and the pump chamber; A state in which the inside of the annular recess is watertightly sealed in an annular recess formed by a cylindrical wall body consisting of a cylindrical part and an outer cylindrical part, and the inner cylindrical part and the outer cylindrical part constituting this cylindrical wall body. an elastic seal member which is housed in the elastic seal member and whose one end is fixed to the sealing; and an elastic seal member which is wrapped around the outer circumference of the elastic seal member and resiliently urges the seal ring toward the vane side. In the water pump, the outer cylindrical portion of the cylindrical wall body is formed with a wavy portion having a wavy cross section, and the outer circumferential surface of the wavy portion is formed on the inner circumferential surface of the bearing portion. A water pump that is placed in close contact with the water pump.
