ABSTRACT:
In a magnetron for a microwave oven comprising a plurality of vanes as an anode and an antenna feeder mounted to the vanes, an antenna feeder fixing device comprising a plurality of radially spaced grooves formed at the upper surface of every other vane so that the antenna feeder is engaged with one of the grooves selected depending on the output of the magnetron. The antenna feeder fixing device can be applied to various models of magnetrons having different outputs, without changing the construction of vanes. This enables modular elements to be used for providing various models of magnetrons, irrespective of different outputs of magnetrons. Only one mold is needed for preparing a single vane construction having a plurality of grooves for various magnetron models, thereby enabling the manufacture cost to decrease.
