Abstract:
A torsional rocking structural component comprising:a movable plate; first and second elastic members for rockably supporting the movable plate, each of the first and second elastic members having a rectangular parallelepiped shape and a rectangular surface; a support for holding the first and second elastic members; and wirings which extend through at least the first elastic member while avoiding a geometric center of the elastic member, the geometric center being in a middle portion of the rectangular surface alone a rocking axis and at a vicinity of the geometric center of the rectangular surface in which a transverse axis crosses at right angles to the rocking axis, and where a Von Mises stress generated during torsional deformation of the elastic member is relatively large, and the wirings further avoiding geometric corners of the elastic member, the geometric corners being at a vicinity of opposite ends of the rectangular surface along the rocking axis and at a vicinity of other opposite edges of the rectangular surface in which the transverse axis crosses at right angles to the rocking axis, and where the Von Mises stress generated during torsional deformation of the elastic member is relatively large, the wirings thereby passing through portions of the elastic member in which a stress generated during torsional deformation of the elastic member is small.
