PROBLEM TO BE SOLVED: To provide a mixer of a simple constitution for setting a setting shaft of an agitating blade structural body on a main shaft and of a low processing cost, not generating the rotating displacement of the setting shaft by the agitating and mixing and easily removing the setting shaft set on the main shaft and changing the direction of the agitating blade. SOLUTION: The mixer is provided with a mixer body 1 into which a material to be mixed is introduced, a main shaft 2 set to be freely revolved in the mixer body and an agitating blade structural body 3 with the setting shaft 21 disposed on the outer peripheral side of the main shaft, having its end secured on the outer peripheral side of the main shaft and agitating an agitating blade 22 set on the setting shaft and agitating the material to be mixed introduced in the mixer body, and a section on which the setting shaft is set on the main shaft is provided with a shaft section positioned on one of the main shaft and the setting shaft and having its cross-sectional shape of a non-circular shape and a hole section positioned on the other of the main shaft and the setting shaft and its cross-sectional shape of the non-circular shape similar to that of the shaft section and engaged with the shaft section.
