51b) is held between the fixing member (53) and the pedestal member (54). Note that the other end of the leaf spring is fitted into and adhered to the grooves (56-1) and (56-2) of the moving member (55).
板ばね装置を他の部材へ固定するには、ねじ（５７−１
）、（５７−２）にて行われる。To secure the leaf spring device to other members, use screws (57-1
), (57-2).
この板ばね装置は、下記に示す問題点がある。This leaf spring device has the following problems.
（１）構成部品が全て、個別に分れているため、組立に
時間を要し生産性が著しく悪かった。(1) Since all the component parts are separated, assembly takes time and productivity is extremely low.
（２）板ばねの厚みが０．０３〜０．１０Ｍと極薄の場
