A turntable device (20) of a microwave oven including: a motor (22) mounted at a lower portion of a cabinet (10); an arm (30) connected with a rotational shaft (24) of the motor (22) so as to be rotatably moved and having first (26) and second (28) rollers at an end thereof; a first tray (32) disposed to be linearly moved on the bottom of the cabinet (10) and having a slot into which the first roller is inserted; and a second tray (34) disposed to be rotatable on an upper surface of the first tray and having a guide rail into which the second roller is inserted. A heating target received in the cabinet can be rotatably, linearly and reciprocally moved so that the cooking target can be quickly and uniformly heated. In addition, because a relative velocity difference between the first and second rollers does not occur, the first and second trays are prevented from being released. |
