されて回転する。(Prior Art and Its Problems) A turntable for a microwave oven is provided with annular protrusions forming legs on the bottom surface, and is supported in a horizontal state by support rollers and rotated. For example, FIG. 4 shows a conventional example, in which a turntable 1 is guided and rotated by a forcefully driven support roller R in contact with the inside of a protrusion 3 on a bottom surface 2 thereof.

る。 Such a turntable is made of heat-resistant glass,
It is manufactured by press-molding molten glass in a mold.
This press forming is performed by supplying molten glass to the center of a mold and using a press to push and spread the molten glass inside the mold. However, turntables are thin, flat, and wide-area products. Because of this, it is difficult to mold glass, and in particular, in the conventional turntable 1 mentioned above, the protrusion 3 protrudes from the bottom surface 2, so molding defects occur at the location of the protrusion 3. do. In particular, since the inner region of the protrusion 3 is a shaded area in the flow direction of the molten glass during press molding, it is not formed accurately, resulting in defects such as unevenness and wrinkles. Therefore, if the inside of the defective protrusion is used as the guide surface of the support roller, a problem arises in that rattling occurs when the turntable is rotated.

ルにある。(Purpose and features of the present invention) In view of the above problems, the present invention eliminates defects in glass molding and enables stable rotation of the turntable. On a glass turntable,
The turntable for a microwave oven has an outer surface of the projection as a guide surface to which a support roller for rotating the turntable comes into contact, and an inner region of the projection as a slope extending linearly from the central bottom surface toward the tip of the projection.

置くために設けてある。 The turntable 10 is molded using a mold shown in FIG.
Molten glass (not shown) is supplied to the center of the bottom mold 20, and then the mold 21 is lowered to spread the molten glass and form it. The figure shows the mold 21 in the upper position after the press forming is completed. In the turntable 10 of the present invention, the inner area of the protrusion 12 is a linear slope 13, so that the molten glass spreading from the center to the periphery during press forming reliably enters the protrusion forming portion of the bottom mold 20, and the outer surface of the protrusion 12 which serves as the guide surface for the support roller R is precisely formed.
No molding defects are generated.
The small projections 14 are provided to allow the turntable 10 to be placed horizontally and stably when it is removed from the microwave oven.
