Abstract
A washer pump for sending, to a nozzle under pressure, cleaning liquid introduced thereinto from an inlet thereof provided in the interior of a washer tank and discharged from an outlet thereof is designed to allow an individual to determine the level of cleaning liquid in the washer tank. The washer pump includes: a cylindrical peripheral wall formed by extending the peripheral wall of the inlet upward so that the upper end of the cylindrical peripheral wall serves as the opening thereof; and a flow passage serving as a through-hole provided on the cylindrical peripheral wall at a lower portion thereof. Preferably, the through-hole is provided on the cylindrical peripheral wall such that the height of the through-hole is almost the same as that of the inlet or below the inlet. The through-hole may consist of a groove vertically extending in the direction from the upper end of the cylindrical peripheral wall toward a lower portion thereof. Thus, the interior of the washer tank communicates with the interior surrounded with the cylindrical peripheral wall.
