PROBLEM TO BE SOLVED: To provide a crusher continuously and effectively crushing various crushing objects including bark. SOLUTION: The crusher includes a crushing rotor 15 disposed with crushing bits 36, and a fixed blade 34 at the outer periphery of the rotor 15 crushing the crushing objects cooperating with the crushing bits 36. The fixed blade 34 is provided with a first inner collision face 60A with a crushing object collision face orthogonal to at least the rotational tangential direction of the crushing rotor 15, and a second collision face 60B with its outer side part located in the counter rotation direction of the crushing rotor 15 at the outer peripheral side of the first inner collision face 60A.
