Abstract: A wire dot printer head of the present invention is configured by being provided with an abrasion preventive member which surrounds an outer circumference of support shafts of a plurality of armatures, between an armature spacer having a plurality of cutouts for respectively accommodating the support shafts of the plural armatures that respectively support printing wires, and a yoke which holds the support shafts of the plural armatures with the armature spacer. With this structure, the support shafts of the armatures do not directly contact with the yoke owing to the abrasion preventive member, thereby restraining abrasion of a surface of the yoke, and preventing a deterioration of printing quality.
