Abstract
A gas sensor including a detecting element having electrodes on first and second surfaces of an oxygen ion conductive solid-state electrolyte; a main fitting having a fitting portion to be fitted into a mounting hole formed on a wall of the pipe defining a flow path for a gas-to-be-measured for holding the detecting element in such manner that the first surface is disposed via the mounting hole at an inner position of the pipe with respect to the fitting portion; a cylindrical cover of which one end is connected to an outer position of the pipe with respect to the fitting portion of the main fitting and the other end is provided with a cylindrical sealing member having an air hole for introducing air to the second surface on one end and a through hole through which a lead connected to both electrodes of the detecting element passes on the other end; and a water repellant filter having gas permeability for closing the air hole, characterized in that the water repellant filter is formed in a sheet shape and mounted on the air hole by means of an inserting member that can be inserted in the air hole.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
