Abstract

PURPOSE:To facilitate extremely the assembling by opposing the lower face of the finger plate to one end part of the spring at the assembling time and then hooking the finger plate hooking part of the spring to the plate after assembling. CONSTITUTION:Main spring 7 is coiled and fixed to base plate 1 before assembling; the lower face of finger plate 10 is made to oppose to one end part of spring 7 when assembling; and the finger plate hooking part of the spring is hooked to plate 10 after assembling. Thus the tension control is given to spring 7 through an automatic transfer hooking applied from plate 1 to plate 10 while assembling. As a result, the assembling can be facilitated extremely for the dial main spring.
