較的重く、高価になりがちな欠点を有していた。[Detailed description of the invention] Conventionally, in straight rod-type brush cutters equipped with a gear chamber that rotates the cutting blade, a rigid shaft made of carbon steel is inserted as a transmission shaft into a rigid operating rod made of high-strength aluminum alloy. However, it is supported using four or five bearings, but this requires high precision during assembly in order to reduce vibrations during work, and also to prevent the operating rod from bending during work. They have the drawbacks of being delicate, relatively heavy, and tend to be expensive.
そこで本考案は、伝動軸としてフレキシブル・
シヤフトを用いることにより、従来の欠点を取り
除いた直杆形刈払機を提供せんとするものであ
る。 Therefore, the present invention was developed to use a flexible transmission shaft.
By using a shaft, the present invention aims to provide a straight rod type brush cutter that eliminates the drawbacks of the conventional brush cutter.
次に図に示す実施例に基づき本考案を詳細に説
明する。 Next, the present invention will be explained in detail based on the embodiment shown in the figures.

めたものである。 As shown in Fig. 2, the brush cutter according to the present invention has a two-cycle motor installed at the upper end of the rigid operating rod 1, which is made of an aluminum alloy or plastic pipe, etc., and has the minimum necessary strength to the extent that it does not interfere with linear work. A gear chamber 4 for rotationally driving a cutting blade 3 is disposed at the lower end of a prime mover 2 such as a gasoline engine.
