PROBLEM TO BE SOLVED: To provide a shredding device capable of maintaining the function of a blade part for a longer time than a conventional device. SOLUTION: In this device, a delivering rotary blade line 32A comprises a plurality of delivering rotary blades 81 mutually provided in parallel at a predetermined interval in a shaft direction of a delivering rotary shaft 31A. Further, this delivering rotary blade line 32A is formed of two types of the delivering rotary blades 81 having a different diameter including two largest-diameter rotary blades 81A the diameter of which is the largest among the delivering rotary blade line 32A and the delivering rotary blades 81 other than the largest-diameter rotary blade 81A the diameter of which is formed smaller than the largest-diameter rotary blade 81A. The diameter D of the largest-diameter rotary blade 81A is formed about 0.5 mm larger than the diameter d of the other delivering rotary blades 81B. The difference between the diameter D of the largest-diameter rotary blade 81A and the diameter d of the other delivering rotary blades 81B is predetermined by a load to the blade part 70 or the like.
