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
A mechanical seal is provided in a space surrounded by the vane, the rotating shaft, and the bearing, 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 with the pump chamber; and a cylindrical wall that slidably accommodates the seal ring and is disposed in the bearing portion in a bubble state. The body is housed in an annular recess formed by an inner cylindrical part and an outer cylindrical part constituting the cylindrical wall body, with the inside of the annular recess being watertightly sealed, and one end of the annular recess is disposed in a watertight manner. The coil spring is wound around the outer periphery of the elastic seal member and elastically urges the seal ring toward the vane. , a generally annular seat ring having a sliding surface in sliding contact with one end surface of the seal ring on one side surface of the mechanical seal side of the vane; and this seat ring is integrated with the vane. When a water pump is equipped with a fixed cushioning material such as rubber, at least one of the inner circumferential side or the outer circumferential side of the cushioning material is attached to the sliding surface of the seat ring. an extending portion extending to an inner circumferential portion or an outer circumferential portion of the seal ring, and the extending portion covers at least one of the inner circumferential portion or the outer circumferential portion and narrows a gap with the seal ring. A water pump characterized by:
