A damper includes a housing having a substantially cylindrical shape and filled with viscous fluid; a rotor portion rotatably supported inside the housing; fin portions projecting from the rotor portion; and deformable portions provided in the fin portions for changing a clearance between an end of the fin portion and an inner peripheral surface of the housing in response to resistance received/ed from the viscous fluid. The deformable portion is provided in the fin portion to allow the fin portion to deform elastically in response to the resistance received from the viscous fluid, and to change the clearance between the end of the fin portion and the inner peripheral surface of the housing. |
