Patent ID: 8851247

Claim:
A damper comprising: a cylinder; a bobbin which is housed in the cylinder and on which a coil generating a magnetic field is wound; a plurality of yokes housed in the cylinder, at least one of the plurality of yokes being disposed at a first axial side of the bobbin, and at least one other of the plurality of yokes being disposed at a second axial side of the bobbin; a magnetic viscous fluid retained on inner surfaces of the plurality of yokes and an inner surface of the bobbin; a plurality of sealing members disposed in the cylinder axially outside the plurality of yokes, the sealing members configured to prevent leakage of the magnetic viscous fluid so that the magnetic viscous fluid is retained; and a shaft which extends through the yokes, the bobbin, and the sealing members and configured to be axially reciprocable relative to the yokes, the bobbin, and the sealing members such that reciprocation of the shaft does not substantially displace the magnetic viscous fluid; wherein the coil, the bobbin, and the yokes are fixed together by a resin.
