    • A pair of substrate portions each being tabular-shaped has side portions located closer to a mirror portion and connected, at both ends thereof in the oscillation axis direction, by a pair of supporting beam portions, and also has outer side portions fixed to a fixing member. An excitation device is formed on at least one substrate portion. The pair of substrate portions is disposed symmetrically in the direction perpendicular to the oscillation axis. A pair of torsion beam portions extends outward from two opposite sides of the mirror portion on the oscillation axis, and each is connected to the center of each supporting beam portion in a longitudinal direction. An edge of the piezoelectric element on an outer side thereof in the direction perpendicular to the oscillation axis is spaced from an outer side portion of the at least one substrate portion in a direction closer to the mirror portion.

    • The invention relates to torsion spring elements for the suspension of deflectable micromechanical elements such as reflecting elements pivotable around a rotational axis. It is therefore the object of the invention to provide torsion spring elements for suspensions of deflectable micromechanical elements which can achieve improved properties in operation with respect to known spring elements. Torsion spring elements in accordance with the invention are made so that they have a changing geometrical design in the direction of their longitudinal axis and thereby have non-linear spring characteristics. The longitudinal axis is in this respect aligned between a clamping or support and the deflectable micromechanical element which is held by at least one torsion spring element. In this respect, a torsion spring element in accordance with the invention can have a straight-line region, which is aligned in the direction of the longitudinal axis, and a fork/branching at at least one end face into which the straight-line region merges.
