A feeding mechanism for sheet staple comprises a reciprocating member ( 12 ) which is provided under a cartridge in which stacked sheet staples are contained and which is reciprocated forwardly and backwardly in response to up and down movements of a driver for driving the sheet staples, a feeding pawl ( 20 ) mounted rotatably by a predetermined angle in forward and backward directions on the reciprocating member ( 12 ) for rotating in a raised direction as the reciprocating member moves forwardly, and a spring ( 13 ) for biasing forwardly the reciprocating member ( 12 ). Each of the sheet staples is fed out forwardly by raising of the feeding pawl ( 20 ). One end of the spring ( 13 ) is engaged in a lower side than a center of rotation of the feeding pawl ( 20 ). The reciprocating member ( 12 ) is urged forwardly through the feeding pawl ( 20 ).
