PURPOSE:To improve a close contact and reduce the leakage of microwaves, by composing a magnetron to arrange an output radiator inside a triangle combining three screws to install the magnetron to the system. CONSTITUTION:A yoke 4 at the foot of an output radiator 6 of a magnetron is projected from a yoke 5 enveloping radiating blades 2, and at the yoke 4, are furnished three installation guide holes or installing screw holes 14a to 14c to install the magnetron to the system. Furthermore, the relative positioning between the holes 14a to 14c and the output radiator 6 is set to position the radiator 6 inside a triangle combining the holes 14 to 14c. In this case, the installing positions are the three points, and the magnetron is installed securely and closely without requesting the flatness of the installing surface. Therefore, the thermal radiation is improved, the leakage of microwaves is reduced, and the safety can be secured.
