PROBLEM TO BE SOLVED: To provide a shredder device having high shredding throughput, capable of instantly, stably performing shredding, efficiently processing a large amount of materials to be shredded at short times, shortening a shredding processing time, suppressing damage, wear, or the like of rotary blades with a less load on the rotary blades, preventing the materials to be shredded from tangling with a rotary cutter for shredding, having simple structure, excellent durability and easy maintenability, and being suitable for mass-production, cost effective and economical. SOLUTION: A shredding mechanism has the rotary cutter A on which a plurality of substantially circular saw-shaped rotary blades 10 are disposed, a lower guide plate 1 disposed below a feeding passage, and an upper guide plate 2 disposed above the feeding passage. The upper and lower guide plates 1, 2 are each disposed with a plurality of blade housing window holes 3, 4 and shreds the materials to be shredded moving on the lower guide plate 1 by the plurality of rotary blades 10 each facing the blade housing window hole 3. this material to be shredded blocks the upward movement of the rotary cutter A for shredding due to the rotation by the upper guide plate 2.
