PROBLEM TO BE SOLVED: To provide a safe and secure blade for a bush cutter which reliably cuts objects to cut such as grass without bouncing them away, and keeps foreign objects or fraction broken by impact from scattering.SOLUTION: The blade for the bush cutter includes: a planar blade body for the bush cutter and a plurality of cutting parts provided on the outer circumference of the blade body for the bush cutter. The cutting part includes: a cutting section which is tilted to the rear side of the rotation direction based on the radiation direction, has a blade, and cuts the objects to cut and a driving-in section which is provided at the front side of the rotation direction of the cutting section, and drives in the objects to cut by gradually reducing the radius toward the rear side of the rotation direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】 草等の刈払対象物を弾き飛ばすことなく確実に切断することができ、且つ、異物や衝撃で破損した破片等を飛び散らせることがなく、安全性の高い刈払機用刃物を提供すること。【解決手段】 板状をなす刈払機用刃物本体と、上記刈払機用刃物本体の外周に設けられた複数の刈払部と、を具備し、上記刈払部は放射方向を基準にして回転方向後方側に傾斜し刃を有していて刈払対象物を切断する切断部と、該切断部の回転方向前方側に設けられ回転方向後方側に向かってその半径を徐々に小さくし上記刈払対象物を上記切断部に追い込む追込部と、からなる刈払機用刃物。【選択図】図3
