Abstract
A dot print head including armatures, supporting parts for supporting the armatures, and torsion bars for supporting the armatures on the supporting parts. Open grooves are formed at least in either the armatures or the supporting parts to place the torsion bars therein, to contain a brazing filler metal therein and to braze the torsion bars to the armatures or the supporting parts by melting the brazing filler metal in the open grooves, and flanges are formed integrally with each torsion bar so as to be positioned between the elastic portions of the torsion bar and the open grooves. The width of the base end of each armature or that of each supporting part is reduced to form a gap between the armature and the supporting part in a width sufficient to form the elastic portion of the torsion bar in a length greater than a predetermined value.
