ABSTRACT:
A print head for a serial dot-printer which includes improved structure to fix each print wire to a pivotable armature. The armature is provided with an arm portion which is made of a stainless steel plate and consists of a pair of mutually opposed side portions and a connecting portion connecting the side portions. Inner surfaces of the front areas of the side portions are welded to each other at the free end portion of the arm. A first supporting full 360.degree. aperture is thus formed between the welded side portions perpendicular to the longitudinal direction of the armature, and a second print wire supporting aperture is formed in the connecting portion and is spaced by a predetermined distance from the first supporting aperture. The rear end of the print wire is inserted through the first supporting aperture until it reaches the second supporting aperture where it is welded to the internal surface of the second supporting aperture in the connecting portion.
