Claims

[Scope of utility model registration request]

Magnets are arranged on both sides of the magnetron body in the axial direction, and the radiator is press-fitted onto the outer periphery of the magnetron body.
In the magnetron, a magnetron body is provided with a U-shaped first yoke plate and a second yoke plate, respectively, so as to surround the magnet, and a plurality of bent pieces facing inward are provided at the ends of the first yoke plate. When provided protrudingly, a first pawl is formed on the bent piece extending in a direction perpendicular to the bent piece, and a taper facing inward is formed on the second yoke plate at a position corresponding to the bent piece. A second pawl having a surface is provided, and notches are formed on both sides of the base of the second pawl, and the second pawl is engaged with and bent by the bending piece, and the tapered surface is bent. A magnetron characterized in that the first yoke plate and the second yoke plate are fixed by locking the first claw of the bent piece.
