構造。 In a liquid pump configured by fitting an impeller 2 that is slidably engaged with a drive shaft 1 only in the axial direction into a casing 3, a plurality of engaging pawls 4 are protruded from a concentric circle on the side surface of the impeller 2. A plurality of concave grooves 6 that can be engaged with the engaging claws 4 are formed on the outer periphery of one side of the seal ring receiving member 5 that fits loosely in the axial direction with respect to the drive shaft 1. A seal structure characterized in that a recess 9 is formed on the other side of the member 5 into which a seal ring 8 that is in contact with the seal member 7 on the outer periphery of the drive shaft 1 can be fitted.
