Claims

[Claims for Utility Model Registration] An incandescent light bulb having a flat crimp-sealed portion formed at both ends and an external lead extending protruding from the outer end surface of the crimp-sealed portion; In an incandescent light bulb with a fixed cap, the crimp-sealed portion of the incandescent light bulb has locking convex portions on one flat surface and the other surface thereof, and the cap includes: , a ceramic holding member for attaching a light bulb, and a rectangular metal cylindrical member; the ceramic holding member includes a cylindrical portion on the outer end side having a through hole into which a covered lead wire is inserted; a pair of connecting protruding plate parts that are formed so as to protrude apart from each other and are fitted and fixed to the outer end part of the metal cylindrical member so as to sandwich one flat surface and the other flat surface of the crimp-sealed part; The metal cylindrical member has a pair of first side plate portions facing one flat surface and the other flat surface of the crimp sealing portion, respectively, and a pair of side plate portions connecting these first side plate portions. The second side plate portion and the pair of first side plate portions each protrude and extend from the inner end side toward the outer end side of the cylinder of the metal cylinder member, and the crimp sealing portion is formed on one flat surface thereof. and a pressure-welding piece, which is pressed from the other side and whose tip end abuts and locks against the locking convex portion of the crimp-sealing portion toward the outer end, and the pair of second side plates. The parts bend and extend from the outer end side toward the inner end side of the cylinder of the metal cylindrical member, respectively, and press the outer end surface of the crimp-sealing part to close the crimp seal with the tip of the crimp piece. and a pressing piece that presses the stop part, and a connecting part between the external lead of the incandescent light bulb and the covered lead wire for power supply is located in the through hole of the cylindrical part of the ceramic holding member. An incandescent light bulb with a cap that is sealed at both ends.
