ABSTRACT:
The optical system supporting device of the present invention comprises an optical element, a holding member for holding the optical element, a supporting member for displaceably supporting the holding member and a driving means for driving the holding member in a predetermined direction, wherein a holding part for gelatinous damping materials is provided on at least one place of the supporting member and a gelatinous damping material is disposed in the holding part. This optical system supporting device is small and light, and is excellent in cotrollability. The optical system supporting device of another embodiment of the present invention comprises an optical element, a holding member for holding the optical element, a fixing member and a connecting member for connecting the holding member and the fixing member, a damping means being provided on at least one place of the connecting member, wherein the damping means comprises a liquid or gelatinous damping material applied around the connecting member, said connecting member being provided with a resistance increasing means at its part positioned in the damping material. With this optical system supporting device high damping performance can readily be obtained and setting of a coefficient of damping can freely be made.
