ABSTRACT:
In order to realize a weight saving and prevent a concentration of stress to thereby obtain durability endurable for high-speed printing, an armature of the present invention has an arm that is formed into a long-sized plate-like shape and holds a printing wire at its end section and a magnetic circuit forming member that is positioned at the other end at the side of the printing wire and has a projecting section projecting from the arm toward the direction in which the printing wire extends, wherein a first inclined surface that gradually inclines toward the projecting section in the direction in which the printing wire extends and a concave-shaped first curved surface that communicates with the first inclined surface and bends inward with a predetermined curvature to reach the projecting section are formed at a first end face of the arm at the side of the projecting section.
