Title:
GAS SENSOR
Document Type and Number:
Japanese Patent JP3861786
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas sensor that realizes a hermetic seal between an isolating insulator at an element side and a housing only with metallic packing.
SOLUTION: In the gas sensor, the cylindrical housing 10 is hermetically inserted with the isolating insulator 3 at the element side via the annular metallic packing 11, and a receiving surface 103 is placed on inside surface of the housing 10. The isolating insulator 3 at the element side is composed of a small diameter part and large diameter part with a large diameter structured, and a taper surface 33 extending from the side of the small diameter part to the outside of a diameter direction. The receiving surface 103 supports the taper surface 33 via the metallic packing 11, and the taper surface 33 and the metallic packing 11 are contacted at the end of the outer circumference of the taper surface 33 where the contacting shape of both of them is a line contact.
