<p>A sleeve-type cartridge case (1) includes an upper half (2), a lower half (3) connected thereto, a connecting protrusion (41) arranged on each side plate (23, 24) of the upper half (2), and a connecting concavity (42) arranged in each side plate (33, 34) of the lower half (3). The connecting protrusion (41) is engaged with the connecting concavity (42) when placing the upper half (2) on the lower half (3). An amount ( delta 1 + delta 1) of engagement of the connecting protrusion (41) and concavity (42) is larger than a difference ( delta 2 + delta 2) between a width (W1) of a cartridge (201) and a distance (W2) between two of the side plates (23, 24; 33, 34) of the upper and lower halves (2, 3) which are positioned inside. <IMAGE></p> |
