Zusammenfassung:	PURPOSE: To economically manufacture the reel pressing spring by suppressing a material loss to the utmost, as well as simplifying a tool. CONSTITUTION: Strip spring steel 73 having a width corresponding to the reel pressing spring 56 to be manufactured is delivered into a cutting position by a grip 74. The strip spring steel 73 is cut by a cutting die 77 into a circular- arcuate or rectilinear shape as an end part of the reel pressing spring, and also arms 56a and 56b are formed with a curved surface with its middle part bendwise formed with a projecting U-shaped bent part 62 as a fitting device.
