ド。[Claims for Utility Model Registration] An armature with a printing wire bonded to its tip is fixed to the other free end of a plate spring with one end fixed, and is equipped with an adjuster screw that presses the plate spring. In a wire dot printing head that prints with the printing wire by rotating the armature by releasing the plate spring to deflect or restore it, the core-opposed surface of the armature is placed at the free end of the plate spring. The plate spring is fixedly arranged in an undeformed state by surface-to-face contact and fixed, and the impact force is adjusted by pressing the plate spring with the adjusting screw to deflect the plate spring from the undeformed state. A wire dot printing head characterized by:
