Claims

[Scope of utility model registration request]

In a brush cutter in which a flexible transmission shaft that can freely bend from an output part and a rod-shaped main rod transmission shaft are connected by a socket and power is transmitted to a cutting blade at the tip of the main rod, one end of the flexible transmission shaft is fitted into one of the sockets. A square hole is formed for the flexible transmission shaft into which the flexible transmission shaft is inserted, and a square hole for the main rod transmission shaft is formed in the other end into which one end of the main rod transmission shaft is inserted. machining the square hole for the flexible transmission shaft by making the inscribed circle of the square hole for the flexible transmission larger than the circumcircle of the square hole for the flexible transmission shaft, and inserting a circular cover between the square holes from the square hole side for the flexible transmission shaft. A brush cutter characterized in that the circular lid is embedded and fixed by extruded cutting pieces.
