Problem to be solved: to provide a cutting tool for a mowing machine which is capable of adjusting the upper and lower rotation of the support angle of the rotary blade of the mowing machine and rotating the rotary blade to the left as in the case of a general type cutting machine, and is attached to the long handle which is used in a general purpose mowing machine.Solution: the mowing head device 10 has an input side housing 12 having a mounting cylindrical portion 14 mounted on the tip of the long handle portion, one side portion 15A of the horizontal cylindrical portion 15 having a left and right two divided structure, and an output side having a vertical portion 15b of the vertical cylinder portion and the horizontal cylindrical portion holding the output shaft The housing 13 is attached to both ends 15a and 15b of the housing 13 so as to be freely rotatable.A first bevel gear 45 meshing with the input side bevel gear 30 is located in the input side housing, and the first bevel gear and the second bevel gear 46 are engaged with the output side bevel gear 50 in the output side housing.The first bevel gear and the second bevel gear rotate the rotary blade 2 leftward relative to the clockwise rotation.Diagram【課題】刈払機の回転刃の支持角度の上下回動調節が行え、回転刃を汎用型の刈払機と同様の左回りに回転させ、汎用型の刈払機に用いられている長柄にそのまま取付けられる刈払機用の刈払ヘッド装置を提供する。【解決手段】刈払ヘッド装置１０は、長柄先端部に装着する装着用筒部１４と、左右２分割構造を有する横筒部１５の一方の片側部分１５Ａとを有する入力側ハウジング１２と、出力軸５１を保持した縦筒部と横筒部の他方の片側部分１５Ｂとを有する出力側ハウジング１３とが、双方の片側部分１５Ａ、１５Ｂを軸回転自在に突き合わせて装着されている。入力側ハウジング内には、入力側傘歯車３０に噛合する第１傘歯車４５が位置し、出力側ハウジング内には、第１傘歯車と連れ回りする第２傘歯車４６が出力側傘歯車５０に噛合している。第１傘歯車と第２傘歯車は、右回りの動力に対して回転刃２を左回りに回転させる。【選択図】図５
