ABSTRACT:
A device for rotating food while cooked in a microwave oven includes a metal housing supported above the oven floor by dielectric feet, and a turntable mounted above the housing. The turntable is rotatable by virtue of a turntable shaft having downwardly extended legs forming a non-circular cross-section, insertable into a similarly configured bore within a drive shaft inside the housing. A detent, pivotally mounted beneath the housing, can be pivoted manually to a locking position in which an arm of the detent engages one of several notches formed in the turntable, to prevent further turntable rotation relative to the housing. A bearing assembly between the top of the housing and the turntable includes an annular frame, and a plurality of ball bearing-containing receptacles arranged symmetrically about the frame.
