PROBLEM TO BE SOLVED: To prevent a crushing material from being heavily dropped inside a casing of a crushing machine, thereby preventing the crushing material from running out from an opening of the casing. SOLUTION: Projections 11 having locking faces 11a directing in a direction facing to a rotary front side of a rotary blade 4 are provided on the upper surface of a bar member 7 setting over the opening 1a of the casing 1. Accordingly, the crushing material running out from the opening 1a of the casing 1 due to air flow generated from the rotary front side of the rotary blade 4 is locked by the locking parts 11a of the projections 11. The heavily dropping of the crushing material inside the casing 1 of the crushing machine 5 is prevented, thereby preventing the crushing material from running out from the opening 1.
