PROBLEM TO BE SOLVED: To provide a rotary blade for a crusher, in which a fixing bolt can easily removed from a fixing bolt hole even after crushing work for shearing crushing of crushing objects.;SOLUTION: In a rotary blade 15 for a crusher, a fixing bolt 21 is inserted into a fixing bolt hole 45, the rotary blade is detachably mounted to a rotary rotor by the fixing bolt 21, and the shearing crushing of a crushing object can be performed between a fixed blade and itself. A deformation suppressing part 55 (tilted flat part) is provided to a crossing part 58 at each opening edge part 56 of a counter boring part 47 of the rotary blade 15. The deformation suppressing part 55 is composed to regulate a protrusion amount of an inward protruded part formed by inward deforming of the crossing part 58 from an opening inner periphery surface 47a of the counter boring part 47 to a size not to catch the inward protruded part by a head part 21a when attaching/detaching the fixing bolt 21 to the counter boring part 47, when crushing the crushing object by the rotary blade 15.;COPYRIGHT: (C)2014,JPO&INPIT
