A microwave oven having an improved configuration of its mounting bracket
to couple a magnetron to a waveguide, to reduce the number of operations
to couple the magnetron to a waveguide, and which is stable in a fixed
state of the mounting bracket to obtain a more efficient cooling effect
for the magnetron. The microwave oven includes an oven body, an inner case
disposed in the oven body, which defines a cooking chamber therein and an
electric component chamber at its outside, a mounting bracket attached to
the electric component chamber, which is provided with one or more pockets
and is provided near the pocket with a reinforcing section to prevent
bending deformation of the mounting bracket, and a magnetron mounted on
the mounting bracket, which has one or more coupling portions to be
inserted into the pocket of the mounting bracket.
