PROBLEM TO BE SOLVED: To provide a jaw crusher capable of reducing a weight of a frame and a manufacturing cost. SOLUTION: Overhang members 15 are detachably provided on lug parts 14 provided on both sides of a side part of a hydraulic cylinder 7 and are fitted to a through hole 16 provided on a side wall 1b of the frame 1, and the hydraulic cylinder 7 is supported on the side wall 1b. A reaction force of a large crushing force is received by an inner side surface of the through hole 16 provided on the side wall 1b and a tensile force and a compression force are only applied to the frame 1. The weight and the manufacturing cost can be reduced without making the frame 1 to a thick thickness with high bending rigidity. COPYRIGHT: (C)2007,JPO&INPIT
