ABSTRACT:
A rotary damper has a movable valve supported on a support projection radially outwardly projecting from a shaft of a rotating member which is rotatably disposed in a chamber filled with a viscous fluid in a casing. Depending on the direction in which the rotating member rotates in the chamber, the movable valve opens or closes a fluid path defined between the movable valve and an inner circumferential surface of the casing. The movable valve may be angularly movably supported on the support projection which is of a circular cross-sectional shape or radially movably supported on the support projection which is of a rectangular cross-sectional shape.
