摘要:
A gas sensor unit including a gas sensor and a sensor cap. The gas sensor includes a gas detecting element, an electrode provided on the gas detecting element and a sensor terminal connecting to the electrode for transmitting an output signal from the gas detecting element. The sensor cap is adapted for transmitting the output signal to an external device. The sensor cap includes a cap terminal electrically connecting to the sensor terminal and an enclosing member bonding to the gas sensor so as to form an internal space in cooperation with the gas sensor. The enclosing member includes a communicating hole through which the internal space is in communication with a space outside the gas sensor unit, and the communicating hole is gas-permeably and watertightly closed by a filter member.

摘要:
A gas sensor including: a cylindrical metal shell; a detection element having a detection portion provided on a front end side thereof; the detection element being fixed inside the metal shell while the detection portion of the detection element protrudes from a front end side of the metal shell; and an element protection cap having ventholes, the element protection cap being fixed to the metal shell so that the detection portion of the detection element is covered with the element protection cap. A crimping cylindrical portion is provided which extends to a front end side of the metal shell. A protrusion portion of the element protection cap which abuts a metal ring packing is provided with concave and convex portions outward along an outer circumferential direction. As such, the metal ring packing is deformed so as to be interlocked with the concave and convex portions when the crimping cylindrical portion is compressively deformed.
