Abstract
A rotary damper includes a housing (1) that has a holding chamber (4), a rotor (2) integral with a gear (2a) disposed rotatably in the holding chamber (4) of the housing (1), and a braking member (3) for controlling the rotation of the rotor (2). The braking member (3) is interposed between the outer periphery of the rotor (2) and the inner periphery the holding chamber (4). A supporting shaft (5) is erected on the bottom part of the holding chamber (4) of the housing (1). A through-hole (7) is bored in the rotor for permitting insertion therein of the supporting shaft (5) in the axial direction of the rotor (2). The rotor (2) is supported through the supporting shaft (5) and the through-hole (7). With this configuration, a stabilized braking force is constantly provided because the rotor (2) does not incline it is being rotated.
