PASSIVITY SPRAY

A manual sprayer is provided to reduce force applied in pressing a handle lever by vertically pushing a plunger from the upper side with a pressing unit by making the handle lever long. A manual sprayer sprays medicinal fluid through the compression of a plunger(30) installed at a spraying container(10) and moving up and down, by interlockingly operating an interlocking arm(40) through the operation of a handle lever(20). A containing case(70) is installed at the rear side of the spraying container. The plunger moves up and down through the operation of the handle lever by connecting the handle lever to one side of the rear lower end of the containing case by a hinge. A hinge shaft is installed at a hinge connecting point of the containing case in a longitudinal direction of the containing case.
