Abstract: Structural simplification and efficient injection state of high-pressure air from a nozzle are ensured. A foreign material removal device is provided with: a cylinder (18) into which air is caused to flow; a piston (22) which is movably supported in the cylinder and feeds the air introduced into the cylinder in a feeding direction as high-pressure air; and a nozzle (6) which injects the high-pressure air fed by the piston. Thus, the piston is moved relative to the cylinder, the high-pressure air is fed from the cylinder, and the high-pressure air is injected from the nozzle, whereby structural simplification and an efficient injection state of the high-pressure air from the nozzle can be ensured.

Abstract: A motor pump for a headlamp cleaner includes a motor, a control circuit board for driving the motor, an impeller rotatable by the motor, a plurality of terminal pieces adapted to be coupled to an outside connector, and a casing. The casing includes a pump chamber having a washer fluid suction port and a discharge port and inside which the impeller is accommodated, a motor housing chamber disposed above the pump chamber and inside which the motor is accommodated, a board housing chamber inside which the control circuit board is accommodated, and a connector portion extending outwardly in a cylindrical shape and inside which the plurality of terminal pieces extends. The connector portion is provided such that one of the terminal pieces is directly coupled to the motor.
