To provide a scattered matter protection cover having a function of safely removing grass entangled with a cutting blade of a brush cutter by a simple operation.SOLUTION: Firstly, a part constituted by integrating the cutting blade covering plate 1, the grip 2 and the main body supporting part 3 is a main body, and a shaft attaching part 4 for fixing to a shaft of a brush cutter is attached to this main body Secondly, the combination of the main body and the shaft attachment part 4 is a mechanism for slidingly passing the connection shaft 5 attached to the shaft attachment part 4 to the main body support part 3, and the main body support part 3, that is, the entire body is kept pressed against the shaft attachment part 4 by the extension force of the spring 6. Thirdly, by sliding the main body toward the handle side of the brush cutter and cutting the cutting blade cover plate 1 and the cutting In order to facilitate the operation of widening the interval between the blades 9 and facilitating the operation of removing the entangled grass by utilizing the rotational force of the cutting blade 9 in the meantime, the grip 2 is provided on the main body.BACKGROUND OF THE INVENTION【課題】刈払機の刈刃に絡まった草を、簡単な操作によって安全に取り除く機能を備えた飛散物防護カバーを提供する。【解決手段】第一に、刈刃被覆板1、グリップ2及び本体支持部品3を一体化して構成する部分を本体とし、この本体に、刈払機のシャフトに固定するためのシャフト取付部品4を組み合わせた構成であること、第二に、本体とシャフト取付部品4の組み合わせが、シャフト取付部品4に取り付けた接続軸5を本体支持部品3にスライド式で通す仕組みであって、且つ本体支持部品3即ち本体全体がスプリング6の伸展力によってシャフト取付部品4に押し付けられた状態を維持する仕組みであること、第三に、本体を刈払機のハンドル側にスライドさせて刈刃被覆板1と刈刃9の間隔を広げ、この間に刈刃9の回転力を利用して絡まった草を取り除くという操作を容易にするため、本体にグリップ2を設けた構成にしている。【選択図】図1
