Claims

[Scope of utility model registration request]

In a print head for a dot printer, which is rotatably supported by a holder and is configured to rotationally drive an armature having a printing wire at its tip to print at the tip of the printing wire, which one of the opposite ends of the holder and the armature A forked end is formed on one side, and the other end is located between the forked parts, and a hollow cross section is formed between each through hole bored in the forked part and the other end. A print head characterized in that an armature is rotatably supported by the holder by inserting and fixing a torsion spring into the holder.
