Various component parts of the stapler, including staple punch which punches out staple pins one after another, a matrix anvil 61 for bending a punched staple pin, arm drive for driving a punching arm of the staple punch, a motor 40 or a drive source for the punching arm etc., are interposed between the casing halves 1a and 1b and thereby directly gripped in the respective positions in the casing when joining the casing halves with each other;
