結果、これらバンド28,30の端部部分及び調節用金具40
が作業者の背中に強く当たるのが防止される。The adjustment metal fitting 40 is inserted through the band insertion triangular metal fitting 36 at the center of the upper portion of the operator side surface portion 24 from above to below. The retaining pin 56 attached to the adjustment metal fitting 40 is inserted into the selected locking hole 46, the shaft portion 58 is positioned in the narrow portion 54, and the flange portion 60 is attached to the rear surface side of the mounting plate 44. Locking hole by contact 46
Is locked. The lower the locking hole 46 into which the fastening pin 56 is fastened, the longer the length of the bands 28, 30 from the locking triangular bracket 32 to the band inserting triangular bracket 36, that is, the shoulder of the operator. The length of the band 28, 30 in the threaded portion is reduced. Therefore, the locking hole 46 for fastening the fastening pin 56 is selected according to the physique and the like of the worker carrying the backpack power sprayer 10. When the worker carries the backpack power sprayer 10 on the back side of the worker, the parts of the bands 28, 30 on the side of the adjusting metal fitting 40 and the adjusting metal fitting 40 are accommodated in the accommodation groove 38, and the operator side surface. The protrusion of the portion 24 onto the surface is avoided. As a result, the end portions of these bands 28 and 30 and the adjustment fitting 40
Is strongly prevented from hitting the back of the worker.
