PURPOSE:To obtain a printing head, wherein the tip of a spring force adjusting means is engaged with a spring member at a right angle when the spring member is deflected by the spring force adjusting means, spring force adjustment management is facilitated, and abrasion resistance of a junction part between the spring member and the spring force adjusting means is improved. CONSTITUTION:An attracting member 9 is atrracted to pole faces 12A and 13A of yokes 12 and 13 by a permanent magnet 14, and a spring member 10 is deflected. Thus strain energy is provided. The spring force related to the strain energy is adjusted by the compression and pulling of a compressing member 19. A taper part 20 is provided at the tip of the compressing member 19. The taper part 20 is engaged with a hole 11, which is provided at the tip of the spring member 10. |
