A damper includes a vessel for accommodating a viscous fluid in its interior; hampering walls for hampering the flow of the viscous fluid; a partitioning member which partitions each of interior portions into two chambers and is provided rotatably; a communicating hole formed in the partitioning member so as to allow the two chambers to communicate with each other via a variable passage whose passage cross-sectional area changes; a flow limiter to limit the flow of the viscous fluid in the chamber into the chamber through the communicating hole, when the internal pressure of the viscous fluid accommodated in the chamber has exceeded a fixed value on the basis of the rotation of the partitioning member; and a resilient structure to resiliently urge the partitioning member in a direction with respect to the vessel.
