Claims

[Claims for Utility Model Registration] A magnetron main body with an output section protruding through a sealed body, an annular permanent magnet fitted around the sealed body, and a shim plate made of a magnetic material on this permanent magnet. A yoke plate made of a magnetic material that surrounds the sealed body, the magnetron body, the permanent magnet, etc., and has a through hole through which the output section is inserted, and the A magnetron comprising an annular gasket fitted between a sealing body and the yoke plate. The shim plate is tightly fitted to the outer periphery of the seal, and one of the shim plate and the yoke plate is provided with a plurality of protrusions, and the other is provided with a plurality of protrusions into which the protrusions are fitted. A magnetron characterized by having a common through hole.
