PURPOSE: A rotating ring for a microwave oven is provided to avoid the deformation of a pin rotatably supporting a roller from a body and to keep sufficient rotational support performance despite long time use. CONSTITUTION: A rotating ring comprises a round body(20), a roller(26) rotatably supported on an outer face(20a) of the body, and a pin rotatably supporting the roller on the body. The pin consists of a lengthwise combining hole(22a), a support pin(22) rotatably supporting the roller, and a fixing pin(24) having serration teeth on the circumference inserted into the combining hole of the support pin. As the pin is restrained from displacing, the roller is reliably supported. The support pin is combined with the fixing pin without hitting on the rotating ring body, an enamel coat of the rotating ring body is protected.
