A portable microwave oven turntable having a base assembly defining a base interior. The base assembly includes a planar bottom and upwardly extending sides supporting a circular base cover member. Within the base interior is a spring motor which may be wound to rotate a drive shaft about a vertical axis. An upper portion of the drive shaft projects from the base interior through the base cover member. Atop the base cover member a drive gear is fixed to the upper portion of the drive shaft. The drive gear has a plurality of radially extending arms having coplanar upper surfaces and opposed lateral edges. A circular tabletop is rested upon the radial arms of the drive gear and tabletop teeth or projections engage the lateral edges of the radial arms. The tabletop projections extend downwardly from the lower surface of the tabletop and project radially inwardly from an annular hub. Rotation of the tabletop is translated directly from the drive shaft via the radial arms. A gear train governs the rotational speed of the tabletop.
