Abstract
Provided is a liquid pump configured to suppress discharge of air from an air pool formed in a discharge-side tank. A discharge-side tank part formed in a housing has a first inner wall surface and a second inner wall surface facing each other in a horizontal direction in an installed position of the liquid pump. The first inner wall surface is formed with a discharge port, and the second inner wall surface is formed with an opening of a discharge-side communicating passage. An air pool is formed in a space in the discharge-side tank part above the opening of the discharge-side communicating passage and the discharge port. A circular cylindrical partition is provided in the discharge-side tank part. The circular cylindrical partition projects from the second inner wall surface toward the first inner wall surface with at least a portion of the cylindrical partition positioned above the opening of the discharge-side communicating passage so as to cover the opening as seen from the air pool side.
