ABSTRACT:
The crisscross fulcrum according to the present invention is formed as a continuous member by fabricating one elastic member in the form of a plate. Therefore, the rocking fulcrum member can be obtained as a precise fulcrum member at a low cost with reduced variations in the spring characteristic and can be easily assembled. Additionally, in the present invention, it is preferable that a heat treatment should be performed on the crisscross spring formed by fabricating the one elastic member in the form of a plate. By the heat treatment performed after fabricating for forming the crisscross spring, the spring characteristic is improved.
