Abstract:
A microwave oven, comprising:a heating chamber for accommodating a food product; a magnetron for supplying microwaves; a rotational antenna formed to allow rotation for stirring the microwaves oscillated by said magnetron; a motor for rotating said rotational antenna; an antenna shaft serving as a rotational shaft for said rotational antenna; and a motor shaft that serves as a rotational shaft for said motor, wherein said rotational antenna is connected to one end of said antenna shaft, and other end of said antenna shaft is fitted to said motor shaft such that said antenna shaft and said motor shaft overlap by a prescribed length in a direction intersecting a direction of rotation of said rotational antenna, and said rotational antenna is arranged such that a gap between said rotational antenna and one of wall surfaces inside said microwave oven is kept smaller than said prescribed length in a direction intersecting a direction of rotation of said rotational antenna.
