PROBLEM TO BE SOLVED: To provide an apron member of rotary working machine for easily attaching and detaching a ground-leveling member in order to prevent adhesion of earth and sand to an apron body part.SOLUTION: The apron member 1 includes: the apron body part 3 that is vertically rotatably connected to a shield cover body part 2 for covering the upper side of a working rotor 5 and covers the rear side of the working rotor 5 the ground-leveling member 4 that is arranged at the side of the working rotor 5 of the apron body part 3 and brought into contact with plowing ground to level the ground and a fifth cover material 21e that is arranged at the side of the working rotor 5 of the apron body part 3 and arranged closer to the side of the working rotor 5 than the ground-leveling member 4. The ground-leveling member 4 is connected to the apron body part 3 by a second connection part 103 and is attached to and detached from the apron body part 3. A fifth free end part 121e being at the end part of the opposite side position in the rear side direction of the fifth cover material 21e is positioned at a position between the second connection part 103 and the working rotor 5.COPYRIGHT: (C)2013,JPO&INPIT【課題】エプロン本体部への土砂の付着を防止するための整地部材の着脱が容易なロータリ作業機のエプロン部材を提供すること。【解決手段】エプロン部材1は、作業ロータ5の上方を覆うシールドカバー本体部2に対して上下回動可能に連結されて作業ロータ5の後側を覆うエプロン本体部3と、エプロン本体部3の作業ロータ5側に配置され、耕耘地面に当接して整地する整地部材4と、エプロン本体部3の作業ロータ5側に配置され、整地部材4よりも作業ロータ5側に配置される第5カバー材21eと、を有し、整地部材4は、エプロン本体部3に対して第2接合部103によって接合されて、エプロン本体部3に対して着脱自在に形成されており、第2接合部103と作業ロータ5との間の位置に、第5カバー材21eの後側方向の反対側位置の端部である第5自由端部121eが位置する。【選択図】図5
