About.

  In general, an ignition device such as a lighter is widely used as a tool for igniting an object such as a cigarette indoors or outdoors. For example, a lighter for cigarettes is widely known as a structure in which a gas ejected from a nozzle is ignited by an ignition element such as a piezoelectric element, and the cigarette is ignited by a flame. Protected against fire extinguishing. An ignition device that ignites gas appliances for cooking and the like includes a relatively long ignition head, and ignites a target object with a flame of fuel gas ejected from the ignition head.

Particularly in the case of an ignition device equipped with the latter ignition head, there is a problem that the gas ejected from the nozzle does not readily ignite under strong outdoor winds, or the ignited flame disappears immediately and the target object cannot be easily ignited. is there. Therefore, for example, Patent Document 1 (Japanese Utility Model Registration No. 3115848) proposes mounting a cylindrical windshield to such an ignition head. In this document, it is proposed that a windshield formed in a cup shape is attached to the ignition head part, and a structure in which a magnet is attached to the ignition head part by a magnet is proposed. In Patent Document 2 (Utility Model Registration No. 3027153), an outer case of a cigarette lighter is formed in a cylindrical shape and fitted into a spiral groove formed in the lighter body, and the outer case protrudes when used outdoors.
