An ignition unit promotes the efficiency of assembly because connections on the high voltage output side and the ground side are completed by a single operation, when an ignition electrode part and a main unit are connected together directly. A guide rail of the main unit is insertion-engaged into a slit between clamp pieces of a bracket so that the main unit is mounted onto the bracket. With the insertion engagement, a high voltage output terminal receives therein a high voltage input terminal of a spark plug supported by the bracket, a plate terminal which is a part of the bracket is driven into a ground-side connection terminal, and a convex portion of a projected piece is engaged into an engagement hole, for positioning and slipping-off prevention.

Ignition unit

A combustion apparatus ( ) is generally composed of a principal part ( ), a supplementary part ( ) and a burner port assembly ( ). Four metal plates ( ) constituting the principal and supplementary parts ( ) are pressed to have in them several protuberances and recesses. These metal plates are laid one on another to form in them some hollow spaces and sealed regions. These hollow spaces communicate with each other to form a thin gas passage ( ) together with a thick gas passage ( ) in this combustion apparatus ( ) in such a manner that its condition of thick and thin fuel combustion is rendered more stable.

Combustion apparatus

A combustion apparatus ( ) with a burner port assembly ( ) comprises an elongated first array of main burner ports ( ) for jetting and burning a fuel gas mixture of a concentration to make main flames. The combustion apparatus ( ) comprises at least one second arrays of auxiliary burner ports ( ) for jetting and burning a further fuel gas mixture of a different concentration to make auxiliary flames, wherein the second arrays of said auxiliary burner ports ( ) extend along the first array of said main burner ports ( ). The burner port assembly ( ) is constructed using inner and outer wall segments ( ) together with outermost wall segments ( ) or bands ( ). One of the bands ( ) faces the corresponding one of said outermost segments ( ) so as to define between them collateral burner ports ( ).
