耗等が防止される。As described above, according to the present invention, a plurality of projections or bent projections gradually shifted in phase in the axial direction of the plug come into spiral contact with the inclined surface on the neck side of the plug head. Since the plug head is pressed toward the front end of the plug head and the contact wall comes into contact with the front end surface of the plug head, the plug head is located between the projection or bent protrusion and the corresponding contact wall. As a result, a reliable electrical connection is performed, and abrasion or the like does not occur even when the engine is vibrated. Also, even if the shape of the plug head varies depending on the plug manufacturer, the plurality of projections or bent projections that are gradually out of phase will surely press against the neck side inclined surface, preventing rattling, poor contact and rubber Wear of the cap cord is prevented.
