Claims (1)

[Scope of utility model registration request] A cylinder whose front end is open at least, a lid that closes the front end opening of the cylinder and is detached by explosive force, an explosive body housed in the cylinder, and a lid body that closes the front end opening of the cylinder and is detached by explosive force; The ejecta stored in the cylinder so as to be ejected forward from the front end opening of the cylinder from which the lid has been detached, and the internal structure located at a partition position between the storage area for this ejecta and the storage area for the gunpowder body. In the cracker, at least the intermediate portion of the cylinder body in the cylinder axis direction is configured to be deformable in diameter by an external pressing force from a direction orthogonal to the cylinder axis direction, and the deformation A compressible explosive body capable of exploding gunpowder by relatively moving it by the above-mentioned external pressing force is bridged between the opposing surfaces in the middle part of the cylinder body in a posture in which the direction of the above-mentioned relative movement is perpendicular to the direction of the cylinder axis. A Kratzker characterized by being held.
