ABSTRACT:
A turntable device of a microwave oven including: a motor mounted at a lower portion of a cabinet; an arm connected with a rotational shaft of the motor so as to be rotatably moved and having first and second rollers at an end thereof; a first tray disposed to be linearly moved on the bottom of the cabinet and having a slot into which the first roller is inserted; and a second tray 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.
