接させてなる管球用口金。 This tube cap has a cap pin through which a lead-in wire is inserted into a plastic cap body, and a tapered guide hole for guiding the lead-in wire into the cap pin, and a small diameter portion of the guide hole. The cap body is provided with a cap pin insertion hole having a diameter large enough to allow one end of the cap pin to be inserted therethrough and to create a gap between the cap pin and the outer circumferential surface of the cap pin, and the small diameter portion is inserted through the cap pin insertion hole. The small diameter portion is made to have a smaller diameter than the hole, and protrudes near the entrance of the cap pin insertion hole so as to partially block this entrance, and is continuous or discontinuous in the circumferential direction on the circumferential surface of the cap pin insertion hole. forming a protrusion with a height that contacts the outer circumferential surface of the base pin;
The tip region of one end of the cap pin is located between the protrusion and the protrusion, and the tip region is expanded into a tapered shape, so that the tapered inner surface of the tip region of the cap pin is aligned with the taper of the guide hole. A tube cap that is smoothly connected to the surface.
