Abstract:
 A damper device is provided with a stator, a rotor, and a viscous fluid for imparting resistance to the rotation or relative rotation of the rotor, the resistance being braking force. An annular seal section comprising a soft synthetic resin is provided by integral molding to the rotor. The stator has an annular space filled with the viscous fluid, and the main section of the rotor is accommodated in this annular space. The annular seal section is configured to be provided with an outer annular portion provided to the outer periphery of the rotor, an inner annular portion provided to the inner periphery of the rotor, and a portion linking the two annular portions.
