Abstract:
A damping device comprising a motion conversion section for converting a relative linear motion between object-attachment portions of the damping device to a rotational motion of a rotation member and a damping section resisting rotational motion of the rotation member,wherein said damping section comprises an outer cylindrical member disposed outside the rotation member, an inner cylindrical member disposed inside the rotation member, an inner peripheral side sealing layer disposed between the rotation member and the inner cylindrical member, and an outer peripheral side sealing layer disposed between the rotation member and the outer cylindrical member; said inner peripheral side sealing layer and said outer peripheral side sealing layer being sealed with a viscous medium so as to achieve a resisting function against the rotational motion of the rotation member; and wherein said rotation member comprises a cylindrical portion supported by the outer cylindrical member and the inner cylindrical member on bearings disposed at both ends of said cylindrical portion.
