摘要： When an insulator of a spark plug receives an external force in a bending direction perpendicular to an axis at a rear end side body portion, a position C where the insulator is supported by a crimping portion via a packing acts as a fulcrum, and a stress is applied between the position C and a position B where the insulator is supported by a ledge portion via a packing. When an insulator is designed in which the balance of size and modulus of section is adjusted so that τA which denotes a proof strength against bending between a rear end position A of the insulator and the position C and τB which denotes a proof strength against bending between the position B and the position C satisfy 0.71≦τA/τB≦1.27, cracks can be prevented.

摘要： A spark plug in which the rising of a ground electrode is more reliably restrained. The spark plug includes a ground electrode having a core portion extending from a proximal end section toward a distal end section via a bent section, a heat transfer portion extending from the proximal end section toward the distal end section via the bent section, and an external layer located externally of the core portion and the heat transfer portion and extending from the proximal end section to the distal end section via the bent section. As viewed on a section of the ground electrode taken orthogonally to a direction along which the ground electrode extends, at least at an intermediate position of the bent section with respect to the direction, the center of the core portion is offset toward a center electrode from the center of the heat transfer portion.

摘要： A developing device frame unit supporting a regulating member regulating the layer thickness of developer on a developer carrier. The unit includes a frame having a seal forming portion, first and second, first and second end seals contactable to the carrier surface to prevent carrier-axial-direction leaking of the developer, and a blade sealer sealing between the regulating member and the frame to prevent developer leaking when the regulating member is mounted. The blade sealer is an elastomer resin material which is injection-molded with a metal mold and in the seal forming portion where the end seals are provided. The blade sealer connects the end seals with each other, and a protrusion provided by a squeezed-out portion of the resin material is provided by injecting, into a space defined by the metal mold, the seal forming portion, and the end seal seals, a resin material volume larger than a volume of the space.

摘要： A spark plug including an insulator and a metallic shell having an outer surface and an inner surface. The outer surface has a taper portion which comes into contact with a peripheral region around a mounting hole of an internal combustion engine, a tool engagement portion, and a trunk portion formed between the tool engagement portion and the taper portion. The inner surface has an annular step portion projecting toward the insulator and an internal trunk portion extending from the base of the step portion toward the rear end of the metallic shell. When the insulator and the metallic shell are fixed to each other by one of either cold and hot crimping, the projected area of the taper portion is at least two times or at least 1.5 times that of the step portion, respectively.
