The inner case 13 is formed of a material having heat resistance and electrical insulation.

  The lid 4 is provided with an outer lid 14 and an inner lid 15 that is detachably attached to the inner lid 2 side of the outer lid 14. Moreover, the rotary body 5 is arrange | positioned at the inner pot 2 side of the inner lid 15 so that rotation is possible and detachable.

  In the outer lid 14, a motor 11, a small pulley 16, a belt 17, and a large pulley 18 are arranged. The motor 11 is a DC (direct current) brushless motor. Further, the motor 11 has a rotating shaft 11a, and a small pulley 16 is fixed to the rotating shaft 11a. Further, the belt 17 is composed of a timing belt and is wound around a part of the outer periphery of the small pulley 16 and a part of the outer periphery of the large pulley 18. Further, the large pulley 18 is attached to the input shaft 19 of the rotating body 5. Thereby, the rotational driving force generated by the motor 11 can be transmitted to the input shaft 19 of the rotating body 5 via the small pulley 16, the belt 17, and the large pulley 18. That is, as the motor 11 is driven, the rotating body 5 and the first stirring member 6 and the second stirring member 7 attached to the rotating body 5 are rotated.

  The outer peripheral edge of the inner lid 15 is in close contact with the upper surface of the flange portion 9 provided on the upper portion of the inner pot 2 when the lid body 4 is closed. Thereby, the space between the outer peripheral edge portion of the inner lid 15 and the flange portion 9 of the inner pot 2 is sealed, and it is possible to prevent the leakage of the stick from there. The inner lid 15 has a steam hole (not shown), and the steam in the inner pot 2 is discharged out of the rice cooker 1 through the steam hole.
