PROBLEM TO BE SOLVED: To provide a mounting structure of a backpack band in which a hook part and a backpack band do not easily enter the bottom of a body part of a working machine when the body part of the working machine of a backpack-type working machine is grounded.SOLUTION: The body part 1 of the working machine includes a pair of support parts 8 and 8 mutually facing at a fixed interval and a shaft part 9 for connecting the support parts 8 and 8. The hook part 12 that is caught by and engaged with the shaft part 9 and a closing body 13 that closes a space between end parts of the opening of the hook part 12 and forms a ring shape with the hook part 12 are arranged at the lower end of the backpack band 3. Further width of the closing body 13 is a size in which the hook part 12 does not enter the gap of a pair of the support parts 8 and 8 in a state in which the hook part is caught by and engaged with the shaft part 9 to restrict the rotation of the hook part 12 around the shaft part 9. Thus, the rotation of the hook part 12 engaged with the shaft part 9 downward is restricted and the hook part 12 and the backpack band 3 do not easily enter the bottom of the body part 1 of the working machine.COPYRIGHT: (C)2012,JPO&INPIT【課題】背負式作業機の作業機本体部を接地させる際にフック部や背負バンドが作業機本体部の下に入り込みにくい背負バンドの取付構造の提供を課題とする。【解決手段】互いに一定の隙間をあけて対向する一対の支持部8,8と、この支持部8,8同士を繋ぐ軸部9とを作業機本体部1に設ける。また、軸部9に引っ掛けられて係合するフック部12と、フック部12の開口の端部同士の間を閉塞してフック部12と共に環形状をなす閉塞体13とを背負バンド3の下端に設ける。さらに、閉塞体13の幅を、フック部12が軸部9に引っ掛けられて係合した状態で一対の支持部8,8同士の隙間内に進入不能となる大きさにし、フック部12の軸部9回りの回動を制限する。以上により、軸部9に係合したフック部12の下方への回動を制限し、フック部12や背負バンド3を作業機本体部1の下に入り込みにくくする。【選択図】図3
