Claims

[Claims for Utility Model Registration] 1. An air flow switching damper device is disposed behind the cylindrical burner body constituting the burner device, and the rear side of the damper device is connected to the feed cylinder, and the front side is connected to the cylindrical burner body. The damper device is configured to communicate with a plurality of air flow paths provided in the air flow path so that air from the cylinder can be switched and sent to the plurality of air flow paths via an air flow path switching damper device. It is constructed by overlappingly abutting a fixed plate having a fixed side through hole and a movable plate having a movable side through hole, and furthermore, the fixed side through hole communicates with each of the plurality of air channels, and furthermore, the movable plate A damper device for switching air flow paths in a burner device, characterized in that a concave portion is formed on the sliding surface of the fixed plate side approximately along the movable side through-hole to minimize the contact area with the fixed plate. . 2. The air in the burner device according to claim 1, wherein ribs are provided protruding from the periphery of the movable side through-hole of the movable plate, thereby forming a recessed portion approximately along the movable side through-hole between each rib. Damper device for flow path switching.
