Patent number: 6383355Abstract: A gas sensor having improved heat resistance and oil resistance. A portion of a cylindrical cover attached to a metallic shell 29 is formed of a bendable resin tube 50. When the sensor is installed in a location susceptible to oil splashes, a rubber member 54 having intercommunicating holes 58 formed therein can be moved to a position where the rubber member 54 is less susceptible to oil splashes, through appropriate bending of the resin tube 50. Thus, entry of oil into the interior of the sensor is avoided. Also, since the resin tube 50 is bendable, the length of the resin tube 50 can be increased so long as an ambient space around the installed sensor permits, thereby decreasing heat transmitted from the metallic shell 29 to the rubber member 54.Type: GrantFiled: June 20, 2000Date of Patent: May 7, 2002Assignee: NGK Spark Plug Co., Ltd.Inventor: Hiroshi Miyata
