ABSTRACT:
Disclosed is an oscillating system arranged so that a gravity center of a movable member and a torsional axis of a resilient support are easily registered with each other to prevent deformation of the movable member due to its dead weight or deviation of deformation from symmetrical deformation, wherein the oscillating system includes a substrate301, a movable member302with hard magnetic members310and311, resilient supports304and305for supporting the movable member for torsional vibration about a torsional axis312with respect to the substrate, and a magnetic field producing device for driving the movable member relative to the substrate, wherein the movable member302has recesses306and307, and wherein the hard magnetic members are fixed while their end portions are aligned with end faces308and309corresponding to the recesses.
