摘要： A spark plug has a housing of a cylindrical shape and an insulator of a cylindrical shape supported inside the housing. A position of an insulator distal end at a distal end of the insulator is arranged equal to or forward of a position of a distal end of the housing in an axial direction of the spark plug. The spark plug satisfies a relationship designated by an equation, −0.064L2+0.26E+0.53≤T≤0.07L2−0.35L+1.36, where T indicates a thickness of the insulator distal end of the insulator, and L indicates an insulator projection length measured from the position of the distal end of the housing to the position at the insulator distal end surface of the insulator.

摘要： A spark plug for an internal combustion engine includes a center electrode, an insulator holding the center electrode inserted therein, a housing holding the insulator inserted therein, a ground electrode joined to the housing so as to form a spark discharge gap with the center electrode, and a stem electrically connected to the center electrode. The stem includes a stem body inserted and held inside the insulator and a terminal exposed from a proximal end of the insulator. The insulator includes a supported portion axially supported by the housing. A heat insulating member is interposed between the stem and the center electrode. A conductive member is disposed inside the insulator so as to pass through the heat insulating member for making electrical connection between the stem and the center electrode. The heat insulating member is located closer to a proximal side of the insulator than the supported portion is.

摘要： A spark plug has a housing of a cylindrical shape, an insulator of a cylindrical shape fitted into the inside of the housing, a center electrode and a ground electrode. No male screw part is formed on an outer peripheral surface of the housing. A housing support surface is formed on an inner peripheral surface of the housing. An outer peripheral surface of the insulator has an insulator support surface which is supported by the housing support surface in an axial direction of the spark plug. The housing has a pressure fitting part to be presses to a cylinder head of an internal combustion engine. A part of the pressure fitting part and a part of at least one of the housing support surface and the insulator support surface are arranged to be overlapped with each other in a radial direction of the spark plug.
