素センサ。[Scope of Claim for Utility Model Registration] (1) A sensor body formed in a cylindrical shape from a metal material, with the outer peripheral side of the tip serving as an attachment part to a vehicle;
An insulating cylindrical body disposed within the sensor body, one end of which is attached to the inner peripheral side of the tip of the sensor body so as to be in contact with the insulating cylindrical body, and the other end protrudes outside of the sensor body to form a closed end. A rounded zirconia tube, an outer electrode and an inner electrode provided on the outer and inner surfaces of the zirconia tube, respectively, and disposed within the insulating cylinder, one end protruding outside the sensor body, and the other end protruding from the zirconia tube. In an oxygen sensor consisting of a contact plate sandwiched between an insulating cylinder and connected to the inner electrode, there is a heat-resistant material between the sensor body, one end of the zirconia tube, and the other end of the insulating cylinder. An oxygen sensor characterized by being filled with a sealant. (2) The oxygen sensor according to claim (1), wherein the sealant is composed of glass and talc. (3) A substantially disc-shaped contact portion that engages with one end of the zirconia tube is formed on the other end of the contact plate, and the contact plate is positioned radially with respect to the zirconia tube. An oxygen sensor according to claim (1) of patent registration.
