DAMPER DEVICE AND IMAGE FORMING APPARATUS

摘要

A damper device having: an input member into which a rotary drive force is inputted; an output member which rotates in accordance with the inputted rotary drive force; a columnar viscoelastic member provided between the input member and the output member; a driving-side pressing member which is attached to the input member and which applies a pressing force on one end surface of the viscoelastic member in accordance with the inputted drive force; a passive-side pressing member which is attached to the output member and which receives a pressing force from the other end surface of the viscoelastic member; a first supporting member which supports the driving-side pressing member such that the driving-side pressing member can turn freely relative to the input member; and a second supporting member which supports the passive-side pressing member such that the passive-side pressing member can turn freely relative to the output member.
