PROBLEM TO BE SOLVED: To provide a crusher which is capable of shortening the release time when the protection means of an anvil functions.SOLUTION: A crusher includes an anvil frame 40 which is installed so as to hold an anvil 34 and so as to be freely rotated to a crushing device frame 20, a wear plate 61 which is installed at the crushing device frame 20 and on which the anvil frame 40 sits, a shear pin 43 which releases a crushing chamber 27 by allowing the rotation movement of the anvil frame 40 when the impact force which exceeds the tolerance acts on the anvil 34, and a through-hole 65 which is installed at the crushing device frame 20 along the outer peripheral surface 66 of the wear plate 61 and which is closed by the anvil frame 40 when the anvil frame 40 sits on the wear plate 61 and which exposes itself by rotating the anvil frame 40. |
