Mounted between the center shaft and insulator to maintain the airtightness. Denso uses the glass seal method.
A special mixture of glass powder and copper powder is charged in the installation section for the insulator and center shaft and center electrode and melted at high temperature. This bonds the
center shaft and the center electrode and fuses the insulator and the metal.
The sealing for both is good and the thermal ratio of expansion is appropriate, so even under harsh conditions gaps do not occur and good airtightness can be secured.
