ABSTRACT:
A swing member device comprises a swingable part supported by a supporting part to be swingable around a torsional axis on a supporting base in at least one intrinsic oscillation mode: the swing member device having a temperature-raising unit for raising the temperature of ambient atmosphere in the region of swing motion of the swingable part, the temperature-raising unit raising the temperature of the ambient atmosphere to enable decrease of an influence of an unsteady dragging force caused by the ambient atmosphere.
