PROBLEM TO BE SOLVED: To provide crushing teeth for a jaw crusher constituted so as to perform attaching/detaching work safely by training a wire rope over the hanging lock parts of the crushing teeth. SOLUTION: The crushing teeth of the jaw crusher are constituted by providing the hanging lock parts 22 for hanging up the fixed teeth 20 (crushing teeth) and inclined projections 24 for smoothly letting a material to be crushed slide to the upper parts of the fixed teeth 20 (crushing teeth). In a state that the wire rope is trained over the hanging lock parts 22 of the fixed teeth 20, the fixed teeth 20 are attached to a crusher main body 1 to perform detaching work. Accordingly, the falling fear of the fixed teeth 20 during work is eliminated and the enhancement of safety is achieved. Further, since the material 5 to be crushed slides on the inclined surfaces of the inclined projections continued to a charging chute 50, the material 5 to be crushed is let slide smoothly even if the hanging lock parts 22 are set to an exposed state and can be charged in a crushing space 15.
