A rotary connector, in which a guide ring is disposed in an annular space in such a manner that the guide ring elastically contacts with the lower side of the cover portion of an inner case, and the intermediate supporting portion of each of a plurality of cylindrical rollers is rotatably supported by the guide ring in the state that the rotation axis of each roller slants, also both end-sides of each roller contact with a flat cable, also the circumference-side of each roller contacts with the upper side of a lower-side-cover. The above structure realizes a highly reliable low cost rotary connector in which a noise caused by the each-other's bumps of the component parts of the rotary connector is suppressed and the stress applied to the flat cable is greatly decreased.

Rotary connector

An oxygen sensor whose sensing element is covered by a cylindrical porous filter cap, prepared by sintering metallic wool such as nickel-chromium alloy wool for protecting the sensing element from damage by mechanical shock and thermal shock due to a high flow pressure of a high temperature gas and for easy determination of sensing response time.
