PROBLEM TO BE SOLVED: To provide a weeder which can achieve efficient weeding and can be easily maintained.SOLUTION: A weeder 1 includes: a support frame part 8 a rotary weeding part 17 journaled to the support frame part 8 and a cover 25 for covering the outer peripheral side of the rotary weeding part 17. The rotary weeding part 17 includes: a rotary shaft 18 rotated at the drive of a driving source 15 and a plurality of wedding part bodies 19 disposed along the axial direction of the rotary shaft 18. Each of the weeding part bodies 19 has a plurality of pulling pieces 21 which are disposed substantially radially along the circumferential direction of the rotary shaft 18 to pull out the weed when the rotary shaft 18 is rotated. The cover 25 includes: an upper side part 26 covering the upside of the rotary weeding part 17 and a lower side part 27 covering the lower side of the rotary weeding part 17. The lower side part 27 is provided with a slit 27 for downwardly projecting a part of the pulling pieces 21 of the weeding part bodies 19. In the slit 28, the opening width dimension is set a little larger than the thickness dimension of the pulling piece 21.COPYRIGHT: (C)2014,JPO&INPIT【課題】効率よく除草を行うことができ、かつ、メンテナンスも容易な除草機を提供すること。【解決手段】本発明の除草機1は、支持枠部8と、支持枠部8に軸支される回転除草部17と、回転除草部17の外周側を覆うカバー25と、を備える。回転除草部17が、駆動源15の駆動時に回転される回転軸18と、回転軸18の軸方向に沿って複数配置される除草部本体19と、を備える。各除草部本体19が、回転軸18の周方向に沿って略放射状に複数配置されて、回転軸18の回転時に草を引き抜き可能とされる引抜片21を、有する。カバー25が、回転除草部17の上方を覆う上側部位26と、回転除草部17の下方を覆う下側部位27と、を有するとともに、下側部位27に、除草部本体19の引抜片21の部位を、下方に突出させるスリット28を、配設させている。スリット28が、開口幅寸法を、引抜片21の厚さ寸法よりも、わずかに大きく設定される。【選択図】図2
