In a brush cutter equipped with a cutting blade unit that is driven by an engine, a motor, etc. and has a cutting blade in the form of a flexible wire, the cutting blade unit has a monabar-shaped hollow housing, and is housed within the housing and is compressed within the cutting blade housing. and a cutting blade bobbin that is clutch-engaged with the housing, the bobbin comprising:
A boss protrusion protruding from the lower part of the cutting blade housing is fitted into and supported by a substantially central part of the bottom surface of the cutting blade housing, and an upper part of the housing is fitted and supported by a support part located approximately at the central part of the top surface of the housing. The bobbin is slidably held by the blade housing, and one end of which is wound around the bobbin, and the cutting blade is pulled out from a window hole provided in the cutting blade housing. The clutch is pressed against the lower end of the boss protrusion to release the clutch engagement, thereby creating a relative rotational speed difference between the cutting blade bobbin and the cutting blade housing, thereby allowing the cutting blade to be paid out from the bobbin. A brush cutter characterized in that it is configured to obtain.
