IGNITOR

PROBLEM TO BE SOLVED: To provide an ignitor in which connection both on the high voltage output side and on the grounding side is completed at a time in directly connecting a discharge electrode part to a main body, to improve assembling efficiency. SOLUTION: Guide rails 42 and 42 in a housing 41 of the main body 4 are inserted and engaged in slits 243 and 243 between holding pieces 242, 241 and 242 in a bracket 2 fixed to a burner case, so that the main body is installed on the bracket. In accordance with insertion engagement, a high voltage input terminal 322 of an ignition plug held on the bracket is received by a high voltage output terminal 45 to be continued and connected. A plate terminal 271 as part of the bracket is thus inserted into a grounding side connection terminal 46 for continuity connection. A protrusion 43 in a protruded member 44 is engaged with an engagement hole 25 to be positioned, and prevented from coming off. COPYRIGHT: (C)2006,JPO&NCIPI
