PROBLEM TO BE SOLVED: To provide a crusher capable of preventing a fixed blade and a rotary blade thereof from being damaged to the minimum when foreign matters such as metal are mixed in a material to be crushed, and drastically reducing the cost by extending the service life of a tool and enhancing the operability. SOLUTION: This crusher has the comb-toothed fixed blade fixed to a pedestal and the rotary blade fixed to a rotary shaft and disposed so as to be engaged with the comb-toothed fixed blade. The crusher turnably and pivotably supports the pedestal to a base end part by a hinge, or the like, and fixes the pedestal to a crasher body. COPYRIGHT: (C)2005,JPO&NCIPI
