ABSTRACT:
A wire dot printer head which has an armature spacer having plural notches accommodating support shafts of plural armatures respectively supporting a printing wire, and an abrasion preventive member provided between the armature spacer and a yoke holding the support shafts of the plural armatures with the armature spacer for prevention of contact between the support shafts of the plural armatures and the yoke. As the support shafts of the armatures, protected by the abrasion preventive member, are not in direct contact with the yoke, abrasion of the surface of the yoke can be suppressed, and degradation of printing quality can be prevented.
