PURPOSE:To facilitate assembling work, by setting a center holder to a dividing system holding a wire from both sides. CONSTITUTION:A printing wire 1 is formed so as to be made thick at one end 1a thereof and functions as a stopper when a coil spring 2 was externally fitted to the wire 1. One end 1a of the printing wire 1 receives impact by an armature to be protruded to the side of a leading end guide 10 against the spring 2. Center holders 4, 5 are divided into two parts so as to hold the wire 1 from both sides. The coil spring 2 is received in the cross-sectional parts of the center holders 4, 5 and a groove 4a for supporting the wire end 1a in a freely slidable manner and a fine groove 4b supporting the fine part of the wire 1 in a freely slidable manner and coming to the stopper of the coil spring 2 are provided to the center holders 4, 5. The wire 1 having the coil spring 2 externally fitted thereto is set to the groove 4b and, subsequently, the holder 5 having a shape left and right symmetric to the holder 4 is engaged with the holder 4 to form a holder unit making the wire 1 freely slidable. |
