PROBLEM TO BE SOLVED: To allow the force which may be provided by an actuator to be restricted in every moving direction. SOLUTION: Operating rods BS1, BS2 of flexural modulus are guided along with the axis in parallel to the staple axis AX by a guide means, are fixed on first ends E1, E2 of the staple mechanism so as not to axially slide, and are freely slidably movable at second ends EA1, EA2. Then at least one of the operating rods BS1, BS2 is applied with the tension or pressure at the second ends EA1, EA2 of the staple mechanism, thereby guide means FM guiding at least one of the operating rods BS1, BS2 is displaced in the direction closing or separation one from another so that the desired moving direction of the actuator is determined. |
