DYNAMIC VIBRATION ABSORBER, AND OPTICAL DEVICE AND IMAGE FORMING APPARATUS INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To improve stability when a vibration absorption member of a dynamic vibration absorber supports a plate member at reduced cost and weight, to improve reliability of a vibration suppression effect.SOLUTION: A dynamic vibration absorber 100 comprises: a plate member 103 that is disposed opposite to a surface of a mirror 45 in which vibration is to be suppressed at a predetermined interval; a support member 101 that is disposed between the plate member 103 and a surface of the mirror 45 to maintain the predetermined interval; and a vibration absorption member 102 that is disposed in a compressed state at a position separated from the support member 101 by a predetermined distance between the plate member 103 and the surface of the mirror 45 to absorb vibration of the plate member 103.SELECTED DRAWING: Figure 1B
