PROBLEM TO BE SOLVED: To provide a crushing bucket which can carry out minute crush by the arrangement of a crushing rotor and a rebounding board. SOLUTION: The bucket 10 is arranged at the tip of an arm of a civil engineering machine, and receives raw materials charged therein. The bucket is comprised of the crushing rotor 14 having a plurality of crushing teeth 18 for crushing the raw materials, on the periphery thereof, and the rebounding board 15 supported in a bucket body 13 in a rocking adjustable manner, for receiving the raw materials. The crushing rotor and the rebounding board cooperatively squash the charged raw materials and minutely crush the same. Then the crushed raw materials are led toward a discharge board 22 which is arranged in an exhaust port 17 at a lower portion of the bucket body 13 and has holes formed therein, and only minutely crushed materials are discharged via the discharge board 22.
