PROBLEM TO BE SOLVED: To provide a jaw crusher in which a drive pulley and a flywheel can be positioned surely without being affected so much by the machining errors of them and a fitting structure can be simplified. SOLUTION: A second fitting part 83 having a prescribed length and a same diameter as that of a first fitting part is arranged on the end part of a main shaft 80, and the drive pulley 38, a shaft fitting bearing 85 and a swing jaw fitting bearing 84 are fixed to the part 83 by using a fitting bolt 89. The pulley 38 can be positioned surely in the shaft direction without being affected by the machining errors of the bore size of the pulley 38 and the diameter of the shaft 80 since the shaft of the part 83 is not taper as usual but straight. The fitting structure can be simplified since the bearing 85 and the bearing 84 are held by the pulley 38. COPYRIGHT: (C)2004,JPO
