ABSTRACT:
The portion close to a rotation axis, of an S-shaped spring portion of a spring consisting of a plate material and supporting a movable member has a narrow width and a portion distant from the rotation axis has a large width. Therefore, if the movable member is rotated, the portion close to the rotation axis has a small spring constant due to bending deformation in the plate thickness direction. If the movable member is moved in other directions, the respective parts of the spring have a large spring constant due to bending deformation and shearing deformation in the surface direction. The accuracy of the supporting spring apparatus is thereby enhanced.
