PROBLEM TO BE SOLVED: To provide a branch crusher in which a fixed blade is turned in a direction escaping from reaction force when an overload is applied to a cutter bit mounted on a rotary drum so that the breakage of a crushing device is prevented, a metallic lump, etc., is not caught into a gap by the turning of the fixed blade and a state for crushing is easily recovered. SOLUTION: The branch crusher 1 is provided with the crushing device 2 having the rotary drum 8 on which the cutter bit 7 is mounted and the fixed blade 10 in a crushing chamber 6, a charging part 3 consisting of a hopper 11 for charging a material to be crushed and a feed conveyor 12 for feeding the material to be crushed from the hopper 11 to the crushing device 2, and a feed roller 19 for feeding the material to be crushed on the feed conveyor 12 into the crushing chamber 6. A fixed blade support 9 to rigidly support the fixed blade 10 is turnably and pivotally supported around the same axis line as the driving shaft 15 of the head side of the feed conveyor 12.
