BLADE FOR BUSH CUTTER

PROBLEM TO BE SOLVED: To enable the extremely easy exchanging of resin blades, which are elastic resin blades for a bush cutter and fixed on the outer periphery in a freely swingable state. SOLUTION: A cutting unit comprises narrow long resin blades 3 having a hole on the base side and a blade holder 2 for holding the resin blades 3. The cutting unit is constructed in such a manner that the front end of a resin blade 3 is inserted from a window 9 formed on the lower board 5, i.e., one of the disc-shaped boards constituting the blade holder 2, the front end side is allowed to protrude outside the blade holder 2, the hole formed on the resin blade 3 is lead to above a holding shaft 6 standing on the upper board 4, and the blade is lowered so that the holding shaft 6 intrudes into the hole, and as a result the resin blades 3 are fixed to the blade holder 2.
