According to the third aspect of the present invention, it is possible to smoothly switch the power source by adopting a push type that can be turned on / off by pressing the above-described switch.

  In claim 4, the base part to which the rotating stirring body and the guard plate are attached and the main body container are detached and separated by screw fitting, so that they can be removed from the base part and immersed in the cleaning liquid to be washed cleanly. .

  The natto stirrer according to the present invention is an electric system equipped with a motor and a speed change mechanism, so that not only children with weak power and elderly people but also foreigners who are not accustomed to using chopsticks can easily stir and a member for stirring natto Is a screw-like spatula that stirs natto, so even granular and sticky natto can be stirred efficiently, and a spatula-like guard plate is placed next to the stirrer at regular intervals. Because it is equipped, even if the container containing natto is a little small, the natto can be efficiently stirred without spreading or jumping out.

  Furthermore, since the switch adopts a push method, it can be rotated by pressing it with a finger and stopped directly when released, so that even if the stirrer is lifted, the sticky thread will not scatter around. The guard plate located on the side of the stirrer protects it from splashing, but it can also be used conveniently as a spatula for gathering together the natto that has been agitated or transferring the natto to rice bowls.

  In addition, since the base portion having the agitated body and the guard plate can be removed from the container main body in Example 2 type, the base portion can be removed from the base portion and then carefully soaked in a detergent solution when necessary. Can provide a wide range of simple, functional and efficient natto mixers not found in
