Abstract: A trigger-type liquid ejector including an ejector main body and a nozzle member. The ejector main body includes: a longitudinal supply tube portion; a trigger mechanism including a trigger portion; a reservoir cylinder; a reservoir plunger; and a reservoir valve. The longitudinal supply tube portion includes an outer tube and an inner tube. A recovery passage is provided between the outer tube and the inner tube. The reservoir valve is provided in the inner tube and configured to allow supply of a liquid from the longitudinal supply tube portion into the reservoir cylinder by being elastically deformed in the vertical direction.
