Claims (1)

[Scope of utility model registration request] An insulating sleeve having a flange at a predetermined position, an earth spring having an engagement hole in the center and a plurality of elastic pieces bent inward from the periphery to have a substantially O-shaped cross section, and a presser foot having an opening at a predetermined position. A crank-shaped sheathed heater connected to a drive source is rotatably inserted into the side wall of the heating chamber through an insulating sleeve, and heats the outer surface of the elastic piece of the earth spring engaged with the insulating sleeve. The presser plate fixed to the chamber side wall is pressed with the inner circumferential edge of the opening to press the insulating sleeve so that it cannot be removed, and the tip of the elastic piece is pressed against the sheathed heater, so that the space between the side wall and the sheathed heater is pressed. A sheathed heater mounting structure for a microwave oven is characterized in that it prevents electrical discharge, prevents radio wave leakage from the heating chamber, and allows the sheathed heater to be rotatably mounted in the heating chamber.
