Abstract

PURPOSE: To increase wave leakage-preventive effect by forming a section through which metal body passes of an outer wall in a heating chamber in a choke structure, and adding a cylindrical cavity with a plane facing the surface of the metal body thereto.
CONSTITUTION: A metal cylindrical cavity C25 is spot-welded to a cylindrical cavity B23 approximately concentrically with glass A21 in a section where a pipe 20 outside an electric heating wire 19 passes through a rear wall 17 of a heating chamber. The gap between a cylindrical cavity C25 and terminal metal fittings A26, B27 has an electorostatic capacity, and a circuit for shorting out high frequency by a condenser being formed in the section. Thus, choke system and condenser system wave leakage-preventive effects are involved
