PROBLEM TO BE SOLVED: To provide a working machine that enables normal alignment when engaging each work body of the foldable working machine.SOLUTION: A working machine includes a tilling rotor, a center work body disposed backward to the direction of travel of the tilling rotor, a side work body turnably connected to the central work body, and an engagement part for engaging the side end of the central work body with the side end of the side work body. The engagement part comprises a male member 29a projectingly provided from any one side end of the central work body and the side work body, and a female member 29b projectingly provided from the other side end. The male member 29a is a member projected from a first surface constituting the one side end toward the second surface constituting the other side end. The female member 29b is the member including two surfaces disposed having a predetermined interval projected from the second surface constituting the other side end toward the first surface constituting the one side end.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2017,JPO&INPIT【課題】折り畳み可能な作業機の各作業体を係合する際に、正常な位置合わせを可能とすること。【解決手段】作業機は、耕耘ロータと、前記耕耘ロータの進行方向に対して後方に配置された中央作業体と、前記中央作業体に対し回動可能に連結された側方作業体と、前記中央作業体の側端部と前記側方作業体の側端部とを係合する係合部と、を備え、前記係合部は、前記中央作業体及び前記側方作業体のいずれか一方の側端部から突出して設けられた雄部材29aと他方の側端部から突出して設けられた雌部材29bとを含み、前記雄部材29aは、前記一方の側端部を構成する第1面から前記他方の側端部を構成する第2面に向かって突出する部材であり、前記雌部材29bは、前記他方の側端部を構成する前記第2面から前記一方の側端部を構成する前記第1面に向かって突出する、所定の間隔を有して配置された二つの面を含む部材である。【選択図】図4
