<p><P>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. <P>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. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
