Abstract

PURPOSE:To suppress the change of pressing force extremely little while preventing the generation of faulty rectification by a mechanism wherein a plurality of spiral springs, whose inner end sides are fixed, are formed in parallel, and a single brush is pressed by means of the free end sides of these springs. CONSTITUTION:A plurality of spiral springs such as two spiral springs 5, 6, whose inner end sides are fastened to a fixed shaft 2, are formed in parallel. Pressing pieces 3 are mounted at the free end sides of each spring, and a single brush 4 is pressed by means of both springs. Thus, the change of pressing force can be suppressed extremely little, and the generation of faulty rectification can be prevented because one spring keeps contact even when the other spring vibrates. Brushes are easily exchanged in such a manner that a plate 7 is formed at the antipressing piece side of one spring 6, and a projecting portion 7a is stacked on the other spring 5. The brush can excellently be pressed by means of one spring even when the other spring is resonated by diverting the natural frequency of each spring.
