    摘要： An ignition coil that can be easily assembled, that assures co-axial alignment of a primary coil, a secondary coil and a center core part, and that generates desired high voltage. A core body is formed to have an outer diameter larger than that of a permanent magnet so that the permanent magnet will not protrude out of the outer peripheral face of the core body. Accordingly, when the center core part is inserted into a secondary spool, the center core part is not caught by the secondary spool and may be readily inserted and assembled therewith. Also, because no bulge is created at the center core part, it is possible to prevent the center core part from tilting within the secondary spool and to readily assure the co-axial alignment of the primary spool, the secondary spool and the center core part. Thus, voltage generated by the secondary coil is prevented from dropping, and high voltage may be applied to the ignition plug.

    摘要： A gate to mold a primary spool of an ignition coil device is placed at a part which does not oppose a main part of a secondary coil in the primary spool, that is, at a part other than a coil winding portion. It is preferred to use a resin having a high dielectric withstanding voltage and a high flowability, such as polybutylene terephthalate (PBT) or polyethylene terephthalate (PET), polyphenylene oxide (PPO)/polystyrene (PS), or liquid crystal polymer. By arranging the gate except at the winding portion, resin deterioration or cracks occur only at a part which does not oppose the secondary coil, that is, at a part where a high voltage from the secondary coil is relatively low. An adequate dielectric withstanding voltage is ensured without winding an insulation tape around the winding portion.

    摘要： A stick-type ignition coil to be directly connected to a spark plug via a spring. A high tension case containing a high tension terminal and a spring is integrally connected to the bottom end of a high tension generating portion of the ignition coil. The high tension terminal and the spring are separately supported in the high tension case before the spark plug is connected to the ignition coil. When the spark plug is connected, the spring is compressed and contacts the high tension terminal, thereby making electrical contact between the ignition coil and the spark plug. Since the spring and the high tension terminal are supported on separate positions in the case, the spring can be properly compressed without being distorted or jammed between the high tension terminal and the case.

    摘要： The apparatus according to the invention separates a cam structure which activates operation of a pre-hemming structure used for supporting a blade available for preliminarily folding a hem flange into two units including a lower cam structure used for pressuring a movable member of the pre-hemming structure in the downwardly slant direction corresponding to the preliminary folding direction and an upper cam structure for activating operation of the lower cam structure. After completing the preliminary folding process against the hem flange, the upper cam structure is retracted to permit the lower cam structure to be free from pressuring force transmitted in the preliminary folding direction by the movable member. In consequence, the preliminary folding blade is securely prevented from repeatedly and uselessly being operated on the way of lifting an upper mold after completion of the hemming process.

    摘要： A stick-type ignition coil have a central core, a cylindrical member, primary spool, primary coil, secondary spool, secondary coil, outer core and a resin insulator. The two longitudinal end corners and faces of the core are covered by respective buffer members. The inner circumferential corners of the outer core is supported by ring members. Some of the members disposed radially inside and other members disposed radially outside of the inside members are held slidably to each other in the ignition coil. The spools are made of resin containing a rubber in excess of 5 weight percent and reinforcing materials. The resin insulator contains a flexible material.
