Claims

[Scope of utility model registration request]

A brush cutter is provided with a transmission shaft 43 for transmitting the power of the engine 7 to the rotary blade 3 inside a connecting rod 5 that connects the bearing body 1 that pivotally supports the rotary blade 3 and the engine 7. A clutch housing 9 that covers a centrifugal clutch 31 of the engine 7 is removably fixed to the engine 7,
Boss shaft 3 of clutch drum 37 of centrifugal clutch 31
9 is rotatably supported on the clutch housing 9, and an engagement shaft 45 is provided at the end of the transmission shaft 43 to be removably engaged with an engagement hole 47 provided in the host shaft 39. An actuating shaft 53 is provided that slidably passes through the clutch housing 9 in a direction orthogonal to the boss shaft 39 and is biased outwardly by a bullet 55, and the inner end of the actuating shaft 53 is connected to the boss shaft. A brush cutter characterized in that the boss shaft 39 is provided so as to be able to come into contact with the outer periphery of the boss shaft 39 so that the boss shaft 39 can be rotated by the sliding movement of the operating shaft 53.
