Amendment December 9, 1980 The scope of claims for utility model registration is amended as follows.

[Scope of claims for utility model registration] (1) Discharge ports are arranged at appropriate intervals in the longitudinal direction,
In a spraying hose for a backpack power spreader, which has a protruding collision plate on the inner circumferential side that causes powder particles to collide and be directed toward the discharge port, a fitting member having the collision plate and a fitting member at each discharge port are provided. A spraying hose for a backpack-powered sprayer, characterized in that the spraying hose has a socket disposed on the outer circumferential side of the spraying hose, into which the fitting member is removably fitted and fixed. (2) The fitting member and the socket have an uneven fitting part that can determine the relative position of the two in the axial direction and change the amount of protrusion of the collision plate on the inner peripheral side of the spray hose. A spraying hose for a backpack-powered sprayer as set forth in claim 1 of the utility model registration claim, characterized in that: (3) The utility model according to claim 1 or 2, wherein the collision plate is upright or inclined with respect to the main body of the fitting member, or has a rounded shape. Spreading hose for backpack power spreader. (4) The fitting member and the socket are arranged so that the amount of protrusion of the collision plate on the inner peripheral side of the spray hose is determined, and the projected area of the collision plate with respect to a plane perpendicular to the axial direction of the spray hose is determined. to change,
The backpack power dispersion according to claim 1, which is a utility model registered claim, characterized in that it has an uneven fitting part that can change the relative positions of the fitting member and the socket in the circumferential direction. Machine spray hose. The brief description of the drawing has been amended as follows. "It is a figure." on page 9, line 20 of the specification is corrected as follows. 14 is a diagram showing still another embodiment of this invention, FIG. 15 is a cross-sectional view taken along the line - of FIG. 14, and FIG. 16 is a cross-sectional view taken along the line - of FIG. Figure 17 is the same as in Figure 14.
18 is a diagram showing the two circumferential positions of the fitting member in the socket in the case of the embodiment shown in FIG. 14, and FIG. 19 is a diagram showing the projected area on a predetermined plane at the circumferential position in FIG. 18. FIG. ”
