Claims

[Claims for Utility Model Registration] (1) In a speed sprayer in which the air passage 24 that guides the air discharged forward from the blower 22 to the sides and upwards is provided at the rear side of the engine room 30, The air guiding member 48 that partitions the room 30 and the air passage 24 has a protrusion 49 that protrudes toward the air passage 24 at the peripheral portion of the upper end so as to form a constricted portion 50 of the air passage 24. and a communication hole 52 that communicates between the engine room 30 and the air passage 24 at a location of the throttle part 50 above the maximum throttle part of the air passage 24. The structure of the blower section. (2) In a speed sprayer in which the air passage 24 that guides the air discharged forward from the blower 22 to the side and upward is provided at the rear side of the engine room 30, the engine room 30 and the air passage 24 are connected to each other. The air guide member 48 that partitions the air passage 24 protrudes toward the air passage 24 at its peripheral portion so as to narrow the air passage 24, and the air guide member 48 that partitions the engine room 30 at a constriction portion 50 downstream of the maximum constriction portion of the air passage 24. An air blowing section structure of a speed sprayer, characterized in that it has a communication hole 52 that communicates between the air blowing passage 24 and the air blowing passage 24.
