PROBLEM TO BE SOLVED: To provide a grass-cutting blade that prevents vines and longer grass from twisting around the root of a rotor in a grass cutter.SOLUTION: With the purpose of preventing grass from twisting around a rotor body 3, there are installed in a plurality of places projections 4 for which the end part on the rear side in the rotating direction of a cutting blade 2 is slightly curved upward. Also, simultaneously, projections 5 which are curved and raised near the center of the rotation are installed on the same diameter circle in a plurality of places. Grass that comes near the axis of rotation is thereby raised upward to ensure the preventive effect of the twisting around.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】草刈り機において、回転体の根元の周囲につるや長めの草が巻き付くことを防止する草刈り刃を提供する。【解決手段】回転体本体3への草巻き付きを防止する為、切れ刃2の回転方向後ろ側のエンド部分をわずかに上方に湾曲させた突起4を複数箇所設ける。また、同時に回転中心に近いところに湾曲して盛り上がった突起5を同一直径円上に複数箇所設けて、回転軸の近くに来る草を上方に持ち上げて、巻き付き防止効果をより確実なものとする。【選択図】図1
