PROBLEM TO BE SOLVED: To provide a crushing apparatus whose case can be restrained from being large-sized by realizing the lowering movement of a movable case into a fixed case and realizing the seating or fixing of the movable case closely to the fixed case. SOLUTION: A fitting part 74 of the fixed case side and a fitting part 84 of the movable case 80 side are arranged at the positions to cause no interference with the lowering movement of the case 80 and fixed to the fixed case and the movable case respectively while an intermediate fixture 90 is interposed between them. The movable case 80 can be lowered downward by removing the fixture 90 from the part 74. The movable case 80 can be fixed closely to the fixed case by closely sticking the fixture 90 to the fixed parts 74 and 84 so that dust-proofing property can be enhanced. A case 31 can be restrained from being large-sized because the parts 74 and 84 are fixed by using a simple structure, namely, using the fixture 90.
