Abstract
An armature support pivotally supports an armature at one end thereof with the armature holding a print wire, wherein the armature support comprises a support member having a pair of arms; through holes formed in the pair of arms and having the same axis, and a penetrating hole formed in a base portion of the armature. The axis of the penetrating hole coincides with the axis of the through holes when the base portion of the armature is disposed between the pair of arms. A torsion spring member comprising a pair of larger diameter end portions, a larger diameter center portion and a pair of smaller diameter portions which interconnect the larger diameter end portions to the larger diameter center portion is disposed with the larger diameter end portions in the through holes and the larger diameter center portion being disposed in the penetrating hole, whereby the spring member is connected to the support member and armature at the larger diameter end and center portions. Soldering holes are provided all on the same side of the print armature assembly to solder the torsion spring to the support arms and armature.
