To surely feed a staple even when the staples of a rolled staple continuous body are disconnected and expanded.

A shaft 45 is mounted in a storage part 44 of a cartridge 43 as a space forming means. The shaft 45 is located not at a center of the circular storage part but at a position eccentric from the center. That is, the shaft 45 is mounted at a lower part with respect to the center of the storage part 44. A central hollow O of the center of the rolled staple continuous body (a) is fitted to the shaft 45. Whereby the staple continuous body (a) can be prevented from being closely kept into contact with an inner wall 44a of the storage part 44, even when a roll of the rolled staple continuous body (a) is broken up and expanded, and the staple 1 can be surely fed.
