このような構成の背負式動力噴霧機１００にあっては、図３に示すように、背負バンド３のパッド部１０を下方に垂れ下げたままの状態では、背負バンド３のパッド部１０と背当部材２との間の間隙は、上下方向に延びる狭い間隙であり、且つ、腕を通す目標となる部分が明確ではないため、作業者が腕を通し難く背負い難い。また、格納時に、薬液タンク４下に下部バンド部１４が挟まってしまったり、地面に下部バンド部１４やパッド部１０の下端部２１が接触し汚れてしまうことがある。   In the backpack type power sprayer 100 having such a configuration, as shown in FIG. 3, in the state where the pad portion 10 of the backpack 3 is suspended downward, the back of the pad 10 of the backband 3 and the back The gap between the member 2 and the member 2 is a narrow gap extending in the vertical direction, and the target portion through which the arm is passed is not clear. Moreover, the lower band part 14 may be pinched under the chemical | medical solution tank 4 at the time of storage, or the lower band part 14 and the lower end part 21 of the pad part 10 may contact with the ground, and may become dirty.

しかしながら、本実施形態の背負式動力噴霧機１００によれば、背当部材２に設けられ薬液タンク４側（背負部１側）へ凹むスリット２０に、背負バンド３のパッド部１０の下端部２１を差し込むことができる。この背負バンド３のパッド部１０の下端部２１のスリット２０への差し込みによって、背負バンド３のパッド部１０が下方に垂れ下がるのではなく持ち上がってパッド部１０が外方へ膨らむように湾曲し、パッド部１０と背当部材２との間に広い間隙Ｓ（図１及び図２参照）を形成できる。すなわち、従来技術のような弾性部材等を不要とし、簡易な構成でパッド部１０と背当部材２との間に広い間隙Ｓを形成でき、腕を容易に通すことができる。   However, according to the backpack type power sprayer 100 of the present embodiment, the lower end portion 21 of the pad portion 10 of the backband 3 is formed in the slit 20 provided in the backrest member 2 and recessed toward the liquid chemical tank 4 side (the backpack portion 1 side). Can be plugged in. By inserting the pad portion 10 of the back band 3 into the slit 20 at the lower end portion 21 of the pad portion 10, the pad portion 10 of the back band 3 is not drooping downward but is lifted and curved so that the pad portion 10 swells outward. A wide gap S (see FIGS. 1 and 2) can be formed between the portion 10 and the backrest member 2. That is, an elastic member or the like as in the prior art is not required, a wide gap S can be formed between the pad portion 10 and the backrest member 2 with a simple configuration, and the arm can be easily passed.

そして、作業者は、間隙Ｓに腕を通し背負部１を背負えば、パッド部１０の下端部２１は自然とスリット２０から抜け、作業を行うことができる。   Then, if the operator puts his arm through the gap S and carries the backpack 1, the lower end 21 of the pad 10 can be naturally removed from the slit 20 and work can be performed.

また、本実施形態によれば、格納時においても、前述のように、スリット２０に、背負バンド３のパッド部１０の下端部２１を差し込むことにより、パッド部１０及び下部バンド部１４を持ち上げることができ、薬液タンク４の下に下部バンド部１４が挟まってしまったり、地面に下部バンド部１４やパッド部１０の下端部２１が接触し汚れてしまうということを防止できる。   Further, according to the present embodiment, the pad portion 10 and the lower band portion 14 are lifted by inserting the lower end portion 21 of the pad portion 10 of the back strap 3 into the slit 20 as described above even during storage. Thus, it is possible to prevent the lower band portion 14 from being sandwiched under the chemical tank 4 or the lower band portion 14 or the lower end portion 21 of the pad portion 10 from coming into contact with the ground and becoming dirty.

また、本実施形態によれば、パッド部１０の上端部は薬液タンク４の前面に接触し、パッド部１０の上部が上方へ膨らむように湾曲しているため、パッド部１０と背当部材２との間の間隙Ｓが上方へ拡大し、パッド部１０と背当部材２との間の間隙Ｓを一層広くすることができ、腕を一層容易に通すことができる。   Moreover, according to this embodiment, since the upper end part of the pad part 10 contacts the front surface of the chemical | medical solution tank 4, and it curves so that the upper part of the pad part 10 may bulge upwards, the pad part 10 and the backrest member 2 The gap S between the pad portion 10 and the backrest member 2 can be further widened, and the arm can be passed more easily.

また、背当部材２は、作業者の背中に当てるための凸部１９が、上下方向及び左右方向に並設され、スリット２０は、上下方向に並ぶ凸部１９，１９同士の間に、左右方向に延びるように設けられているため、上下方向に並ぶ凸部１９，１９同士の間（凹部）を利用してスリット２０を設けることができる。   Further, the back support member 2 is provided with convex portions 19 to be applied to the operator's back in the vertical and horizontal directions, and the slit 20 is provided between the convex portions 19 and 19 aligned in the vertical direction. Since it is provided so as to extend in the direction, the slit 20 can be provided by using the space between the convex portions 19, 19 arranged in the vertical direction (concave portion).
