DAMPER, WASHING MACHINE, AND WASHER/DRYER

摘要

Disclosed is a damper that obtains damping force through fric tion resistance resulting from the viscosity of a magnetic viscous fluid, and that is positioned on the outsides in the axial direction of a lower yoke and an upper yoke, a seal being disposed on one side (bottom) thereof and a seal being also disposed on the other side (top) thereof. As a result, the magnetic viscous fluid is sealed in both outer ends in the axial direction of a section that is filled with the magnetic viscous fluid, and the leakage thereof can be prevented. Also, as air is not led into the section that is filled with the magnetic viscous fluid, it is possible to favorably maintain the density of the magnetic viscous fluid in said section that is filled with the magnetic viscous fluid, and it is possible to prevent the occurrence of a decrease in damping force.
