475号)。2. Description of the Related Art Conventionally, a crusher for crushing wastes such as plastic and metal cans has been constructed by fixing a crushing blade and a crushing blade on a single drive shaft in a skewered manner. It is known that a fixed comb blade is provided so as to face the above to crush a plastic molded product or the like (see, for example, Japanese Utility Model Laid-Open No. 61-3461). Furthermore, a large shred cutter and a small crushing cutter are fixed in a skewered manner on two drive shafts that are supported in parallel with each other, and are provided between the small crushing cutters that are opposed by the two drive shafts. It is known to have a fixed blade and rotate two drive shafts in opposite directions (for example, US Pat. No. 5201).

被破砕物の食い込みができなくなり、破砕能力がなくな
るため頻繁に固定櫛刃周辺の手入れが必要であった。In the former of those described in the prior art, since the coarse crushing blade and the fine crushing blade provided on the drive shaft are opposed to one fixed comb blade, the object to be crushed is crushed. When crushing, the object to be crushed flies by equilibrium force between the rough crushing blade and the fixed comb blade, or between the fine crushing blade and the fixed comb blade and dances in the machine frame. Furthermore, if the peripheral speed of the fine crushing blade is smaller than that of the coarse crushing blade, the crushing ability will drop significantly, or if the crushed object will stick to the fixed comb blade until there is no gap with the outer diameter of the rough crushing blade or fine crushing blade. Since it is impossible to bite the object to be crushed between the rough crushing blade and the fixed comb blade and between the fine crushing blade and the fixed comb blade, and the crushing ability is lost, it is necessary to frequently clean around the fixed comb blade.
