Claims (1)
用される環状の圧力センサーにおいて、内部電極
、圧電素子、パツキン等が積み重ねられてなる積
層体が環状の開口部を形成した金属外被内に収納
され、上記パツキンが金属外被の開口部から外部
へ突出しその先端縁がプラグの絶縁体の段部面に
当接するよう形成されてなることを特徴とする点
火プラグに内蔵する圧力センサー。 In an annular pressure sensor that is used by being built into the head of the metal shell of a spark plug, a laminate consisting of an internal electrode, piezoelectric element, packing, etc. is housed in a metal jacket with an annular opening. A pressure sensor built into a spark plug, characterized in that the gasket is formed so as to protrude outward from an opening in a metal jacket and its leading edge comes into contact with a stepped surface of an insulator of the plug.
