OXYGEN SENSOR, AND INTERNAL COMBUSTION ENGINE AND TRANSPORT APPARATUS PROVIDED WITH THE OXYGEN SENSOR

摘要

There is provided an oxygen sensor which is highly waterproof in a high-temperature environment and yet allows for downsizing. An oxygen sensor according to the present invention includes: a sensor element having a detection section for detecting oxygen; a housing, the sensor element being insert at one end thereof in such a manner that the detection section is exposed; a cylindrical member provided at another end of the housing; a sealing member for sealing the cylindrical member; and a terminal portion connected to the sensor element. The sealing member has a throughhole, and is made of a heat-resistant resin. The terminal portion is press-fitted in the throughhole of the sealing member.
