スチロール等の発泡樹脂製の間隙材（５）を嵌着した。(1) shows a holder in the shape of a covered cylindrical frame with an open bottom made of synthetic resin, etc., and a cylindrical frame (2) made of paper or synthetic resin is supported on the tip side inside the holder (1). The lower part of the frame (2) is closed inward by a bottom plate (3) made of a conical mountain-shaped metal, and the inside is filled with a gunpowder such as black gunpowder or an explosive such as dynamite (4). ing. Then, a gap material (5) made of a foamed resin such as styrene foam to which an epoxy adhesive (9) is attached is fitted into the enlarged-diameter space at the root of the holder (1).
又前記ホルダー（１）の中間部（６）は空間のまま又は
発泡スチロール等の発泡樹脂等が充填しである。The middle part (6) of the holder (1) may be left open or filled with foamed resin such as styrofoam.
