To provide a self-submerging type warning flare capable of emitting smoke over a long period of time while suppressing enlargement in size.SOLUTION: A self-submerging type warning flare 2 includes a wooden columnar body 10 including an ignition hole 14. A bottom cover 20 to be weight is attached to a bottom unit of the columnar body 10. A plurality of ignition powder tubes 200 serially connected by a fuse 50 and an ignition device 100 for igniting the leading ignition powder tube 200 are stored inside the columnar body 10. A plurality of cylindrical storage spaces 12 communicated with the ignition hole 14 for storing the plurality of ignition powder tubes 200 are formed in the columnar body 10. The plurality of cylindrical storage spaces 12 are serially communicated by having adjacent cylindrical storage spaces 12 coupled with each other by a communicating hole 16. A self-submerging device 30 is provided in between the cylindrical storage space 12 at beginning of the line and outside of the columnar body 10. The ignition powder tubes 200 lit last in lighting order is stored in the cylindrical storage space 12 where the self-submerging device 30 is provided.SELECTED DRAWING: Figure 3

    【課題】大型化を抑えつつ長時間の発炎を可能にした自沈式発炎筒を提供する。【解決手段】自沈式発炎筒2は、噴炎孔14を有する木製の柱状本体10を有する。柱状本体10の底部には重りとなる底蓋20が取り付けられている。柱状本体10の内部には、導火線50によって直列に接続された複数の炎薬管200と、先頭の炎薬管200に着火させる点火装置100とが収容されている。柱状本体10には、噴炎孔14と連通し複数の炎薬管200を収納する複数の筒状収納空間12が形成されている。連結孔16によって隣接する筒状収納空間12同士が連結されることで複数の筒状収納空間12は直列に連通している。列の先頭の筒状収納空間12と柱状本体10の外部との間には自沈装置30が設けられている。自沈装置30が設けられた筒状収納空間12には、着火順序において最後に着火される炎薬管200が収納される。【選択図】図3
