    Abstract: A syringe-shaped spraying device includes: a barrel; a nozzle; a packing disposed therebetween; and a core disposed inside the nozzle. The nozzle is connected to a connecting portion provided at a front end of the barrel. The nozzle has a first facing surface facing a front end surface of the connecting portion and a second facing surface facing an outer circumferential surface of the connecting portion. The outer circumferential surface is provided with an annular recess portion, and the second facing surface is provided with a first annular protrusion portion and a second annular protrusion portion. By engaging the first annular protrusion portion with the annular recess portion, the packing is compressed in an axial direction by the front end surface and the first facing surface. The second annular protrusion portion is in pressure contact with the outer circumferential surface of the connecting portion entirely in a circumferential direction.
