1. A fluid pump, comprising:
a housing that has a shaft hole extending in an axial direction and a pump chamber communicating with the shaft hole; a drive shaft that is provided inside the shaft hole and rotated about an axis by power from a power source; a rotational bearing provided inside the shaft hole and supporting the drive shaft rotatable an impeller that is provided inside the pump chamber and coupled to an end portion of the drive shaft; an electromagnetic clutch that is provided in the housing and establishes or blocks transmission of the power of the power source to the drive shaft; a mechanical seal that is located between the impeller and the rotational bearing and is configured by a first sealing member and a second sealing member facing in contact with each other, the first sealing member being provided in an inner circumferential portion of the shaft hole and the second sealing member being provided in an outer circumferential portion of the drive shaft; and storage means that is formed so as to communicate with the shaft hole in the housing and stores fluid leaking from the mechanical seal, wherein the electromagnetic clutch has a core portion that houses a coil for generating a magnetic field, and establishes or blocks the transmission of the power of the power source to the drive shaft by switching between supply and non-supply of electricity to the coil, the storage means has a fluid storage portion that communicates with the shaft hole between the mechanical seal and the rotational bearing and is opened to an end portion in the axial direction, and an attachment member for attaching the core portion to the housing seals the opening of the fluid storage portion. |
