摘要

This invention relates to a magnetron with a device for coupling an antenna feeder to an evacuation tube. The coupling device comprises a male engaging member formed at an upper end of the antenna feeder and a female engaging member formed at a lower end of the evacuation tube and adapted to fittably receive the male engaging member. The female engaging member comprises a hollow boss and a pair of slits formed at the hollow boss. The coupling device couples the antenna feeder to the evacuation tube before the evacuation tube is tipped off and enables the antenna feeder to be maintained at its initial set position.
