2. Description of the Related Art Conventionally, a flame reaction member has been provided in the vicinity of a fuel gas ejection portion of a burner such as a lighter or torch, and a flame ignited by the fuel gas ejected from the fuel gas ejection portion is colored in various colors. The technique of improving the aesthetics is proposed. (For example, Jitsukai Sho 60-86761, No. 50-11677
(See Publication No. 9).

However, the flame-color reaction member in the invention disclosed in the above publication has a problem that the color development duration is short because the flame-color reaction material is applied on the support in a trace amount.

In order to solve this difficulty, a plurality of thin wire rods having a wire diameter of about 0.1 mm are twisted together to form one support, and the support extends in the vicinity of the center of the support. A single spiral winding part is formed around an axis perpendicular to, and the spiral winding part is twisted so that its central axis is parallel to the extending direction of the support, and then a flame is applied to cover the spiral winding part. A flame reaction member has been proposed in which a color reaction product is adhered and solidified on a spiral winding portion.

By the way, the larger the amount of heat of the flame applied to the flame-colored reaction product, the shorter the time required to start color development, and it is desirable that the heat of the flame effectively acts on the flame-colored reaction product. Therefore, it is necessary to make the diameter of the support as small as possible to reduce the amount of heat conducted to the support, while the support is required to have sufficient strength to support the flame reaction product. The support is formed by twisting a plurality of thin wires.

In order to prevent the flame-colored reaction product from falling off the support due to the heat generated by the flame of the combustion instrument, the spiral winding portion is formed by rotating it by about 90 degrees, and the flame-colored reaction product is attached to the support. The surface area of the body is enlarged.

However, as described above, the process of twisting a plurality of wire rods is troublesome, and the process of rotating the spiral winding portion by about 90 degrees is difficult because it is difficult to machine, so that it is formed by hand.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a flame reaction member for a combustion instrument, which includes a support body that reduces the labor required for processing and reduces the manufacturing cost. To do.
