<p><P>PROBLEM TO BE SOLVED: To obtain an ignition plug for reformer that is easy to manufacture. <P>SOLUTION: A discharge rod 58 is inserted through an insertion hole 52 formed through an insulator 51. A taper hole 54 linked to the insertion hole 52 while expanding outward in diameter is formed in the insulator 51, and a sealing member 60 is disposed between the periphery of the discharge rod 58 and the inner periphery of the insertion hole 52 in the insulator 51. An injection hole 56 linked to the taper hole 54 and opened outward is formed in the insulator 51, and sealing glass 74 injected from the taper hole 54 side through the injection hole 56 is fused and solidified. Furthermore, the insulator 51 is inserted through an insertion hole 66 formed through a fastening member 64, a taper hole 68 linked to the insertion hole 66 while expanding outward in diameter is formed in the fastening member 64, and an injection hole 70 linked to the taper hole 68 and opened outward is formed. A sealing member 72 is disposed between the periphery of the insulator 51 and the inner periphery of the insertion hole 66 in the fastening member 64, and sealing glass 76 is fused and solidified. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
