It is formed with an impeller (1d) installed inside the pumping room (1a), a pumping unit (1) with a grounding protrusion (1i) at the bottom of the outer wall of the pumping room, and a rotating shaft (2a) of the electric motor (2) on the impeller (1d). In a known electric water pump that is connected and rotates the impeller (1d) with the force of the electric motor (2), the outer cylinder (4) is covered so that a water storage chamber (3) is formed around the outer peripheral wall (2b) of the electric motor (2). Thus, the inner end 4a of the outer cylindrical body 4 and the inner end 2c of the outer circumferential wall 2b are connected to the outer connection part 1f and the inner connection part 1g formed on the outer wall 1e of the positive receiving part 1, respectively. Insert the packing (5) (5a) into the joint and fasten it with the bolt (6), and communicate with the pumping chamber in the gap formed between the inner and outer connection parts (1f) (1g) of the outer wall (1e) of the pumping unit (1). A cooling device made by drilling a hole (7) to allow water to communicate between the water storage chamber (3) and the pumping chamber (1a) around the electric motor (2) is protected on the outside of the power supply unit (8) of the electric motor (2). An electric water pump is formed by inserting the packing (11) (11a) into the sealing part (9a) connected to the water storage chamber (3) by covering it with a cover (9) and fastening it with a bolt (10) and a nut (10a) to form a leakage prevention section. It is public.

However, the conventional water pumps described above are expensive to manufacture, difficult to manufacture due to their complicated structure, and there is no coupling installed on the motor of the water pump, making it difficult to control the straightness, concentricity, and advance angle when transmitting power from the water pump body to the pump. It was difficult and had the disadvantage of consuming a lot of energy in power transmission.

In particular, the conventional water pumps described above require a separate installation stand, are structured in such a way that they cannot be directly connected to the manager, and are very inconvenient to install.
