の刈刃取付け装置。 The main operating rod has an engine at one end, a gear case at the other end, and a cutting blade holder attached to the output shaft of this gear case. In a mower blade mounting device for a brush cutter, which is equipped with a mower blade fastening base to which the mower blade is attached, the mower blade is attached to the output shaft by a screw connection, and the attachment base is spline-coupled to the output shaft. The tightening device comprises a fastening base having a click stop mechanism, and an operation ring fitted onto the fastening base and biased to push out a ball of the click stop mechanism. The mounting base has a slider that can be moved outwardly by centrifugal force generated by rotation, and a friction plate that is pressed against the cutting blade by the outward movement of the slider. By being pulled down along the axis, the clip stop mechanism can be released and the clamping base can be released from the mounting base, and the cutting blade is fixed by friction between the friction plate and the cutting blade retainer at a predetermined rotation speed or more. A mower blade attachment device for a brush cutter, characterized in that it is configured as follows.
