A flush type sprinkler head with an improved structure is provided to cause a heat collector to fall together with an inner loading plate without being completely separated from a body, and to achieve fast and precise watering. A flush type sprinkler head includes a heat collector(31) installed outside a frame(26) screwed to a body(22) for sensing a fire and a fuse metal(32) installed between the heat collector and a locking screw(33). An upper inside of the frame forms an inclined face to which a retaining ring(27) being cut in part is connected. The retaining ring is connected to oblique surfaces(29a,30a), each having an inner loading plate(29) pressing a spring sheet(23) to shut a water outlet(22a) and an outer loading plate(30) connected to the inner loading plate, respectively. At the lower end of the frame, protrusions(26c) are formed so that the inner and outer loading plates descend together with the heat collector and are seated at the protrusions of the frame.
