Zusammenfassung:	PURPOSE: A rotary damper is provided to prevent noise and damage to furniture when a door of the furniture is closed by reducing the closing speed of the door. CONSTITUTION: A rotary damper comprises a damper case(410,410'), a vane member(420), a crank(430), space members(460,460'), and an opening and closing unit(470). The damper case has moving spaces(402,402'). The vane member is formed in the moving spaces of the damper case and is rotated. One end of the crank is fixed to the vane member, and the other end selectively interferes with a link. The space members are formed in the inner side of the damper case. The opening and closing unit is formed in one side of the space members and opens and closes moving passages(484,484') formed in the space members.
