A rotary shaft that is rotatably supported, an engaged portion is formed on an upper portion of the shaft, and a lower portion of the shaft has a different diameter cross-sectional shape; A rotating shaft of the electric motor is provided with an engaging part that can engage with the engaged part of the rotating shaft, and a blade is attached to the outer periphery of the boss that can rotate with respect to the supporting shaft, and the upper part rotates. And a cutter member provided with at least a pair of elastic arms that engage with and sandwich the different-diameter cross-sections of the shaft.

[Advantage of the Invention] Since the present invention is configured as described above, after the cooking material is put in the state where the boss of the cutter member is attached to the support shaft of the container body, the lid is placed on the upper part of the container body. The lower part of the rotating shaft is attached so as to be clamped by the elastic arm of the cutter member. Next, after the drive member is attached to the lid so that the engaging portion of the rotating shaft engages with the engaged portion of the rotating shaft, the cutter member rotates when the electric motor is driven. The cooking ingredients are cooked by. At this time, since the upper part of the rotating shaft is supported by the lid and the boss of the cutter member is supported by the supporting shaft of the container body, the bending of the rotating shaft during the cooking operation is prevented.

After the cooking work, the drive member and the lid are removed from the container body to take out the cooked cooking material inside. Further, since the cutter member can be removed from the lower part of the rotary shaft, the cutter member can be easily washed.
