。[Scope of Claim for Utility Model Registration] An armature having a printing wire bonded to its tip is fixed to the other free end of a leaf spring whose one end is fixed by a yoke, and at the same time, by pressing the pressure receiving part of the leaf spring. It is equipped with an adjusting screw that adjusts the amount of elastic deformation of the leaf spring, and the armature is rotated by attracting the core with magnetic flux or releasing it from the core to bend or restore the leaf spring. In a wire dot printing head that performs printing, the adjusting screw is arranged on the outside opposite to the central core side with the fixed end of the plate spring fixed by the yoke as a border, and a plate corresponding to the tip of the adjusting screw is arranged. A pressure receiving portion of the spring is disposed in a cantilever shape with the core side as a fixed end and facing above the yoke, and the adjusting screw is disposed on the yoke at a position opposite to the pressure receiving portion. A wire dot printing head characterized in that a hole is formed through which a pressure receiving part that is elastically deformed by being pressed by the wire escapes.
