Claims

[Claims for Utility Model Registration] (1) An annular storage space whose axis coincides with the motor shaft is formed in a frame that can be attached to a motor shaft, and the storage space is free from inertia due to its own viscosity. A damper made of a viscous body that is deformed by (2) The damper according to claim 1, wherein the viscous body is made of a gel-like polymeric material. (3) The damper according to claim 1, wherein the viscous body is composed of a gel-like substance of two or more polymeric substances having different specific gravities and which are laminated concentrically. (4) The damper according to claim 1, wherein the viscous body comprises a gel-like material of a polymeric substance and a heavy material having a higher specific gravity than the gel-like material. (5) Registration of a utility model characterized in that the frame body is composed of a boss that can be attached to the motor shaft and two annular frame plates that are fixedly arranged in parallel to the boss at a predetermined distance. A damper according to claims 1 and 4. (6) The frame body is press-fitted onto the motor shaft.
The damper according to claims 1 and 4, characterized in that the damper is constituted by two annular frame plates and a spacer disposed between the frame plates. (7) The damper according to claims 1 and 4, wherein the frame body is made of an annular film having a U-shaped cross section.
