PROBLEM TO BE SOLVED: To provide a planting machine that can simplify a shape of a cover body when a rotating member and an electrical component provided at a supporting member to swing a marker arm up and down are covered with the cover body to be protected.SOLUTION: The planting machine includes: a control part 43 which supports a marker arm 36 at a supporting member 41, and controls the lower side swinging of the marker arm 36 an electric actuator 44 which makes the control part 43 perform upper and lower turning operation through the rotating member 46 and a detection sensor 47 which detects the turning position of the rotating member 46, wherein the marker arm 36 is made to perform upper and lower swing with the control part 43 by a biasing member 42 which biases a marker arm 36 to a lower side. The marker arm 36 and the control part 43 are arranged at a front side of the supporting member 41, an electrical component 55 including the electric actuator 44 and the detection sensor 47, and the rotating member 46 are arranged at a rear side of the supporting member 41, and a cover body 48 which covers and protects the rotating member 46 and the electrical component 55 is provided.COPYRIGHT: (C)2013,JPO&INPIT【課題】マーカアームを上下揺動させるために支持部材に設けられた回動部材及び電装品を、カバー体によって覆って保護するにあたって、該カバー体の形状を簡素化できる植付作業機を提供することを課題としている。【解決手段】マーカアーム36を支持部材41に支持し、マーカアーム36の下方揺動を規制する規制部43と、規制部43を回動部材43を介して上下回動作動させる電動アクチュエータ44と、回動部材46の回動位置を検出する検出センサ47とを備え、前記マーカアーム36を下方側に付勢する付勢部材42により、マーカアーム36を規制部43とともに上下揺動する植付作業機であって、マーカアーム36及び規制部43を支持部材41の前面側に配置するとともに、電動アクチュエータ44及び検出センサ47を含む電装品55並びに回動部材46を支持部材41の後面側に配置し、回動部材46及び電装品55を覆って保護するカバー体48を設けた。【選択図】図4
