Claims

[Scope of utility model registration request]

a butt-fitting surface on the outer peripheral edge of the first casing on which the motor output shaft is rotatably supported so as to pass through the first axis, and a bottomed cylinder shape with one end open and the other end closed; A cylindrical liquid inlet centered on the first axis is formed protruding on the outer surface of the bottom of the cylinder, and a cylindrical liquid discharge port, which is discharged by rotation of an impeller provided at the tip of the motor output shaft, protrudes from the outer peripheral surface of the cylinder. In the electric liquid pump configured to be assembled by butt-fitting the cylindrical end of the second casing, the butt-fitting surface of the first casing and the cylindrical end of the second casing are assembled. Butt-fitting between the two is based on a second axis that is eccentric with respect to the first axis, and butts between surfaces that are perpendicular to the second axis, and inner and outer cylinders with the second axis as the axis. In addition, the inner surface of the cylinder bottom of the second casing is provided with an impeller-facing surface formed in a planar circle centered on the first axis, with an outer diameter larger than this. An electric liquid pump characterized in that the inner surface of the cylinder bottom on the side protrudes toward the first casing side.
